Ctrl+v does not work on my Windows 7 64 bit machine. Ctrl+x works.
Right clicking on the text and choosing "Cut" works. Right clicking and choosing "paste" right after does not work.
This happens in every application on my system. Notepad, word etc.
It seems the problem happens when I have Open Office open. Doing some copying/pasting in that program and then trying in other programs is when the error will occur. If I close Open Office everything returns to normal.
My Open Office does not have any keyboard shortcuts set to Ctrl+v.
