Crashing eM Client when answer

My Em client crashes every time I answer an email. - Windows 11


See @Gary post from the following thread

This seems like the Windows 11 bug with UI automation, which Microsoft are aware of.

You can try eM Client in Windows 8 Compatibility mode, which bypasses that part of Windows 11, and see if there is any difference.

To do that, on the Windows Start Menu, find the eM Client entry and by right-click choose Open File Location.
In the window that opens, right-click on the eM Client shortcut and choose Properties.
In the window that opens, choose the Compatibility tab.
Then select “Run this program in compatibility mode for”
Select Windows 8 and click on OK.
Now open eM Client using that Start Menu entry you just edited.
