Jazz I tried the Task Manager thing but it was visible when I opened KSP, I checked that full screen was enabled in KSP game menu. I'm going to try and validate the steam game cache and then reinstall your patcher, just to see if there was a problem with what I did. Just to be sure, you place it in the folder, along with the source files, with the launcher and the GameData files and all that stuff, just not in any particular files. Tetryds, thanks for replying. I held alt after alt-tabbing and the game went straight to the desktop, there is a flash of those boxes but it goes away. EDIT: I validated the Steam cache and it re-acquired 5 files. I then used your patcher, everything went okay but still I can see the task manager in KSP.
