Although it will take time to do, I would go through and test one file at a time -- install one script and see if you have the problem. If not, uninstall it and install another one. Yes, it will take a lot of time to test all of them (unless you're lucky and it's the first one you test), but unless you can figure out where the problem is, that's your only real solution.

Just a note, though... You might try using Ctrl-Break when you're having problems (hit it 4-5 times in a row). Then, see if you see any error messages (check status and your active window). If so, that should give you an idea of where the error may be located.
