If I use the tag2find toolbar to search in my tags, and I type in a 'v', then I would automaticaly paste what's on my clipboard, instead of typing the 'v'. Every other letter works fine, and it's not like I'm holding down the 'ctrl'-key. It's quite irritating that I first have to place the letter 'v' on my clipboard, before pressing the 'v' makes a 'v' appear in the bar.

//edit: opening and closing the toolbar did the trick, but after using it for another half hour, it started doing it again.
