>Done that already, but also checked the free floating sessions (yes, Thomas guessed right), but these at least I could check separately and they were OK. It's the forms that worry me - I can run the test on the active forms, which is near worthless, as I also need to check a bunch of modal forms which pop up only under certain conditions... trying to launch each one of them (even if I knew all of the cases when they'd pop up, and how to create such cases) would take me days.

Then I only have to worry if there's another setting that may appear later :).

aVcxClasses() and aProcInfo() will come handy... too bad it won't work on .scx files but that can be done by opening these as tables... well, here's a nice little project...
