Short cut issues

Hi all. Running SKP2024 on windows and noticed that all of a sudden my undo function, ctrl z, is not working anymore. Also the measuring tool is seemingly glitching in that I can’t divide with the shortcut keys, enter-backslash-2-enter, (same as in Mac OS )anymore.
Any suggestion are appreciated.
Thank you

Please complete/update your forum profile. Are you using Windows on a Windows PC?

Have you tried a cold reboot of your computer?

The Divide feature with Move/Copy or Rotate/Copy uses a forward slash, not a back slash. Never has used a back slash for arrays.

Thank you for your input. I think I start with the reboot. I tried both back and forward slash. Keep my fingers crossed.
Thanks again.
