Running anything else along with Mala?
Having Mala run anything on exit?
Having Mala confirm exit, or just exit?
If confirming, does it lock up before or after it asks for confirmation?
The only thing I can think Mala does on exit is write to mala.ini
Do you have mala.ini marked as read only or something weird like that?
Another thing out of curiousity...are you using a stripped down version of XP?
