What happened:
Customer report:
I have a logitech mouse M510 with a button set to BACK. When BACK is pressed at Main startup window an unrecoverable blank window is created. Windows X does not kill window. I have to use Task Manager to kill window.
[Have replicated using a Corsair mouse with a side button mapped to BACK, like for a web browser, on a Windows 10 system.]
What did you expect to happen?:
Nothing Input should be ignored.
How did you reproduce it?:
Press mouse button function BACK at Main startup window.

Thanks.
v2.0.26 is ready for testing and is currently available through the staging update channel.
In case of an automatic update, the UI app requires a manual close and restart to apply the changes.
Verified fixed on v2.0.26, Windows 11, first I was able to reproduce the issue on v2.0.25 and then I was able to confirm the fix in the latest beta version. The issue is no longer reproducible.
