I've had this problem, probably since installing version 4.0x, but it's gotten annoying enough to ask for help with it. I do a "copy" or "cut" on one PC, move the mouse over to the other PC in seamless mode, and then "paste". Nothing happens, or worse, the 'paste' causes the browser window to hang. All other functions work great! Oh, an update: I was having problems with Multiplicity on my PCs, which were being blamed on Webroot. The issue turned out to be

Hi Sean, There certainly is something weird going on. Everything was fine until Win 11 24H2 some months ago. That disconnect issue cleared up when Webroot was uninstalled, and there's a bug in WR that they are trying to fix. Now, with the 2025-05 quality update, it's become unstable again. My inclination is to blame Windows, but their bugs are features which everyone else needs to accommodate. It would be helpful to have some sense for how to solve this.<

OS Build 26100.4061 One clarification: Some of the disconnects are Multiplicity only, and the Ethernet connection is maintained. These tend to be quick dropouts and restarts. Then there are ones where Ethernet and M4 both drop, and it takes several seconds for the Ethernet to reconnect, then M4.

Hi, After the Window 11 24H2 2025-05 quality update and .net update this week, M4 KVM started disconnecting from my secondary and losing the Ethernet connection on the primary totally and then reconnecting several seconds later. It will then crash the Ethernet (and M4) again a few seconds to a few hours later. I had this problem some months ago that was related to having Webroot installed, but I don't have it installed now. FYI Webroot is still working to resolve t

To give an update: This is my Multiplicity 4.01 pro installation on two Win 11 24H2 (latest updates) PCs in shared KM mode. I'm getting the secondary dropouts on a regular basis, and often the dropout is accompanied by the primary losing its Internet connection. Multiplicity then reconnects to the secondary, and then a few moments later, the connection to the Internet resumes. So Multiplicity 4.01 is crashing the primary computer's Internet connection on Win 11 24H2.

Just to add a note: I have a similar setup at home, where both PCs are Win 11 24H2 and M 4.01, so we can't blame M 3.6 or the Win11/Win10 differences, and the home setup does not have Backblaze. I get secondary dropouts there, too... not every 30 seconds, but still at an annoying level.

OK, since the other thread was getting long, and the problem is still not resolved, I'm starting a new thread. Windows 10 primary, 22H2 (company PC, not upgradeable), M 3.6 (not upgradeable). Windows 11 secondary, just updated to 24H2 a day ago after putting it off, and thinking that I may have identified the issue with the outdated ethernet driver and possible Backblaze interference. Came in to work this morning and the secondary is dropping off the primary every 30 secon

Here's an update on the M 3.6 crashing issue. I was working on my Win 10 22H2 (not upgradeable) primary with M3.6 connecting to my Win 11 23H2 secondary, which has been very stable, when Dell command update popped up with an Intel driver update for the Optiplex 7070's Intel I219-LM onboard ethernet chip. It installed the Intel driver dated 10/25/2020 version 12.19.0.18. It did not require a reboot, and after it installed, M 3.6 could not maintain a stable connection between

Well, I just ran updates and updated Multiplicity 4 on both computers, and I'm not seeing the same screen on the primary computer as you show above. II see the same secondary screen as you show, and configured that.

Houston, we have a problem.... I upgraded from 3.6 to 4.0, buying the upgrade license for the basic version because I only use the KM function as I work between two computers and two screens. However, I have lost the log off function (I have to go to each computer to log off, it used to be that a single-logoff did both) with this version, as well as the 'log into the primary, and it then logs into the secondary' function. I realize that this

Hi, This blog has been quiet for a while, so I'm wondering if there's been any discoveries or patches on the Stardock side that relate to this connection instability issue. I have not had the time to play with updating both primary and secondary to 24H2 and seeing what happens, since it's stable with 23H2 (getting in final grades, doing taxes, new semester...). However! I have another multiplicity-linked computer set, no VPN, wired ethernet, primary running Win 10

No VPN, I have Webroot installed on both PCs for years, so I doubt that's an issue. Dell Command Update is wanting to do a BIOS update and a couple of other drivers. I'll install those and see what happens, then try MP4 on both.

OK, I installed 24H2 on the secondary PC again (wired connection), and tried using the IP address two ways: First by checking the "always use IP address x.x.x.x" box, and then by deleting the secondary and reinstalling it on the primary PC using it's IP address as the name (after I did this, I did change the 'display name' to the PC name that I use). Same problem. I'll be moving the cursor or clicking something on the secondary PC, when the cursor freezes, and after a coup

Sean, I am using the secondary PC name, not it's IP address. The computers are both wired. I am also using Multiplicity 3.6, Build 00105, I haven't upgraded to 4.0 yet, but it sounds like user stardock 641 above is having the same issue with 4.0 that I'm having with 3.6.

FYI, I rolled back the 24H2 feature update, and the disconnect problem went away. So it's pretty clear that the 24H2 update is causing the disconnect issue. As 24H2 is rolling out, are there any others finding this problem?

It's a wired connection, and I get the error and disconnect while I am actively typing through the primary keyboard onto an app on the secondary computer. There's definitely NOT a 6-second lack of reply... well, there might be a lack of reply from secondary to primary, but the primary to secondary information flow is happening when I get the disconnect. With a wired connection, I'm not sure what 24H2 would do to make the ethernet connection unreliable.

This week I installed Windows 11, 24H2 feature update on one of my PCs that is seamlessly connected to the master PC, running Win 11, 23H2. They are connected with Multiplicity 3.6, build 00105. After the 24H2 update, every few minutes, the computers disconnect, and I get a Multiplicity pop-up on the primary that the secondary was not responding quickly enough. After a minute or so, the two reconnect and it works for several minutes, until they disconnect with the 'not respo
