Ok I finally got around to reinstalling OFP after being away for 10 months. I spent 3 of those in the hospital and several more in physical therapy after a car wreck. :'(
Anyway, I've lost the ability to alt tab. Sometimes it works, but most of the time all I get is the windows cursor, but the OFP editor is still in the forground, although I can't control it. It's a pain in the butt to have to quit OFP to make a change to a script and then restart OFP every time. Sometimes if I keep pressing it, I'll eventually get OFP back to the foreground.
I have Windows XP Pro, and I didn't have this problem before. The only thing that I know has changed is I've installed SP1, and DX9.
Any clue how to fix it? OFP and my desktop are different resolutions, I've tried setting them to the same, but it didn't work.
