I upgraded from 10.04 to 10.10 and having been trying to fix this issue for a couple of weeks with no luck.
Copy and pasting text is really wonky. Sometimes it works sometimes no matter what I do and copy will paste instead.
I use different programs, thunderbird, firefox and gedit. Sometimes it is fine others I can click all different ways with no luck at all
Things I have tried:
Installing various clipboard programs. (Seems to be making the issue worse)
I tried using the esc key also
What does not work: Ctrl + C, Ctrl + V, mouse right click nor Edit > copy and paste.
I have a Microsoft wireless 1000 keyboard/mouse and dual monitors. Just as a test I put the live CD of 10.04 and could not get the problem to duplicate. Nvidia graphics card...
Am I so messed up may have to wipe and reinstall 10.04?
