I've got to wonder if there's some POS (not Point Of Sale, the OTHER meaning) Adobe-ish shortcut in your startup folder that's setting it back. Go to Start-->Settings-->Taskbar (may have longer name depending on which OS you're on) and click the Remove button. Look for a folder called Startup and open it up. It might possibly be in there. While you're there check out what's in there and see if you REALLY need it loading at startup. Some of that crap will load unnecessarily but still work when you run the program. Supposed to make it open faster or some garbage.

Hmmm...maybe Apple should base their next operating system on something rock stable, like a flavor of Linux or even BSD. Then they can throw their pretty crap on top and their friendly user interface and it might be a decent OS. THAT would be cool.
