If you mouseover the window does it repaint?

I agree with what pelaird said above.  Hoping for a speedy repair.

It's an intermittent bug.  Only experienced it three times with 12 workstations over the last couple of weeks.

This bug is still NOT fixed in the latest update today (v1.36).  This is a serious bug.  Please make sure it  was reported to the developers.  Thank You.

It happened twice again.  This is an intermittent bug that has been confirmed by other users.  Thanks.

I can't reproduce the issue on my system. Can we have more information to try to reproduce it please. Can you post what your setting on this page please.

Also can you write down steps that I can try to reproduce it on my system.

Thank you,

Okay, I've changed my Start11 Search setting same as your, but I still can not reproduce your issue on my system. Might need more time. Something come to mind while I was testing my system. Do your system also search things on network drive/share drives too? Which I don't have on my system.

Thank you,

Please try purge and reinstall steps as mention here : [Link]. Just make sure to redownload the latest version from your account page. Reboot after the purge. Reinstall and reboot again after the installation. Retest and report back here.

I just want to report I'm having the same issues, and have been having them for months (since installing Start11 on this machine). I've tried uninstalling and reinstalling, and installing both beta and non-beta versions.

I'll try the full purge and report back, but I thought my info might be helpful. 

For me, search sometimes works, but will suddenly stop working in the middle of a search and never return (until a restart). As an example: Today I was searching for a file, and while typing the name a list of results appeared. Then with another keypress, the results went blank. Deleting the last letter typed didn't bring them back. All search results have been empty since then, no matter what I type, no matter what category is selected.

Just happened again...

All the computers with the issue are running Windows 10 Pro or workstation 22H2 build 19045.2965 and Start11 v1.45.
I have not been able to reliably replicate the issue on demand yet. One search and it's fine and another search seconds later and it's broken.  This happens about once a month or two.  The only way to fix Start11 in this state is to reboot.  Restarting the Stardock Start11 service or terminating task Start11_64.exe doesn't help.  Here is a screenshot. If I get more info, I will post.   Thank You!

No, but I will next time and report back.  Thanks.
