MKVToolNix wont expand

Hello.
I installed latest edition.
Program starts, I can see it on the task bar but will not expand. It is always minimized.
Used to work ok. Installed previous version still the same.
I am using Windows 11.

Any ideas?
Thank you
John

Welcome!

Try removing the settings file & see if that fixes it. That’s where the window positions to restore are saved.

I cannot find this file…

Somehow the problem is fixed.
Thanks for the help.
