Cant copy paste anything

I cant copy and past from one script to another. Control -c and Control -v dont work. I am able to select the text and right button cut/copy but I cant paste it anywhere.

Any guidance would be greatly appreciated

Obvious questions, but you haven’t said what you’ve done to isolate or troubleshoot the problem:

1. Is this a problem only with MATLAB or with every application (notepad, etc.)?
2. Does the problem remain after rebooting?
3. Did you install any new applications?

Also, do the following alternative shortcuts to Cut/Copy/Paste work?

Cut - Shift-Delete

Copy - Control-Insert

Paste - Shift-Insert
