On the right keyboard numpad (PC), the keys do not switch note durations

Pressed...
And everything else seems to be checked ...
I restarted the program, the computer too ...
2 days ago I wrote notes - everything was OK ...
Now I opened MS3 in parallel: everything works ...
That's why I decided to post here...

Yes
Factory reset helped
Version 4.0.2
In this regard, there was a proposal to add the ability to save settings in a separate file.
Sometimes these settings take more than an hour.
In my case: a lot of custom toolbar movements and a whole cascade of custom time signatures for recording choir parts in measures:
1/4, 2/4, 3/4 ... 45/4;
1/8, 2/8, 3/8 ... 45/8;
1/16 ... etc.

Thank you for being so incredibly efficient!
And especially - for this wonderful program!

p.s.
Very interesting - what it was (smile) ...
In the logs, probably, such a bug is not visible ...

I also noticed that the MS4 reacts more slowly ... on all devices ... it takes longer to load ... it plays the record harder (on a laptop it's very difficult).
I sincerely wish you all the best!
We will try to help with our feedback (smile) ...
