Could be that there's a code in the URL which Objectdock doesn't understand or recognize. Which creates possible confusion, and therefore a "crash". My suggestion, if you are open to it,  is to find another way to retrieve weather information.  Rainmeter is a great app which can display weather information. Does Objectdock crash when you assign any other websites to the dock? I rarely use a dock, and when I do, it's Rocketdock, but I don't remember ever having assigned websites to the dock. Just different apps or programs. Or you can try assigning the weather app that comes with Windows 10 or Windows 11, depending on which OS you are using. There is also a weather thing that is part of the taskbar in some of the newer versions of Windows 10 and all versions of 11.  

If I had to guess, I would say it is something in the ObjectDock code that restrict the number of characters in a file name. This URL has 288 characters. Try another URL that has as many or more characters in the address, and see if it displays the same issue. Then try another URL that has less than 256 characters.

By default, Windows 11 uses a path length limitation (MAX_PATH) of 256 characters. I found this site which tells how to change this limitation.

I'm not sure if this will help with ObjectDock issue, but it's worth a try.

EDIT: I tested this by changing the Registry entry "LongPathsEnbled" to 1. I created the shortcut with your URL and tried to add it to a dock and ObjectDock still crashes.

I'm pretty sure my original assumption is correct. I created a new shortcut using your URL shortened to 'https://www.metoffice.gov.uk/weather' and it works.

Hi Peliard 

Your shortened address does not get me to the local Coven interactive Weather Map which is what I require

I also believe that the windows restriction in entry length is not the answer as the link works fine on a desktop shortcut but if I drag the desktop shortcut and drop it on Objectdock it causes object dock to shut down and the link is lost

I think it could be that Objectdock is misreading one of the characters in the link causing it to crash

Hi all – we have a fix available internally, but there is no timeline for a release. The issue is due to a path that is too long. ObjectDock currently only supports paths up to MAX_PATH which is 256 characters. They behavior can get a little imperfect (automatic image handling and naming won't work), but we've extended this limit now to 2000 characters. @pelaird, since there is no timeline for a release, you can get a copy of this patched copy at https://www.dropbox.com/scl/fi/vlrovrah5jl356fkv4x86/ObjectDock-Long-Path-Fix.exe?rlkey=cppa14p6ha28t3xwmhok06gn6&dl=0

I hope this helps!

Exit ObjectDock. Copy the downloaded "ObjectDock-Long-Path-Fix.exe" to C:\Program Files (x86)\Stardock\ObjectDock and use it to start ObjectDock.

You can of course also rename the download ObjectDock-Long-Path-Fix.exe to ObjectDock.exe and overwrite the excisting one in C:\Program Files (x86)\Stardock\ObjectDock.

I tested on my system. And, it working for me. Refer my short video below.

I just noticed that it was a tab dock.
