I was trying to take a picture on my screen and paste somewhere, but since it wasn't an image I pushed print scrn sysRq on my keyboard and then went to my desktop. I wanted to paste it there, but the paste option wasn't there, only a paste shortcut option. I pushed that and a message popped up and it said something about an active desktop and then I had to save a file somewhere and then it asked am I sure that I want to proceed or something like that. I said yes and then all my icons stopped having a transparent background, but instead, a blue background. Also, now, when I move windows on my desktop, there is a ghost behind them (It looks like they duplicate as I move the window).
What can I do to make my icons transparent again and fix the trailing windows problem?
BTW, I have WIndows XP.
