Hello, watermagic.
I did some testing just there, and I didn't see the problem you mentioned in the most recent version or on 5.02.
If what I'm understanding is correct, what you're saying is that when you press the letter 'v', it pastes what you have on your clipboard without pressing control?
If yes, then my testing concludes that it may be a problem on your side, as it didn't happen to me during my testing.
Try updating to the latest version, and see if the problem still persists, if so, then it could be a hardware issue.
