Undo doesn't work

Can you provide an example file where you weren't able to undo?

Got the same problem with GG Classic 5 on win 10.

Most classmates also have the same problem.

In the attached file I continuously get no response with undo, when I try to do something with vector v, and then try to undo.

I advice reinstall GG

it seems that some files in prefs folder are corrupted

Thanks, great test-case!

Workaround for now: close properties view, save file, close GeoGebra, reload

HiThe workaround is not a good workaround.

When you save and close, you loose your undo list anyway, and need to correct everything after all...

And when you open the file again, it works partially with the properties window closed. But that's a window that you need a lot,... and when you open it again it takes 5-15 clicks on undo for each step of undoing...
