it seems Greenshot is the tool I've searched very long for. Unfortunately, if I doubleclick on greenshot.exe I got the error message (german):
"Die Anwendung konnte nicht richtig initalisiert werden (0xc0000135)."
So there are problems with the initialization.
Anyone knows why? I'm running Win XP.
obviously you don't have the .net redistributable package installed on your computer.

Have fun with Greenshot!
Works now like a charm - thanks alot!
