Downloaded the beta Macphex 8 last week, it worked great 3 or 4 times, but now it the window closes up immediately after the program opens and the icon disappears from the dock. I've deleted the program and reinstalled it to no avail and I even tried using Macphex 7 but nothing works. I assume it's corrupt preferences because if I log-in as a different user the program works just fine. What I need to know is which preferences were installed with this program so I can trash them. I've been in the Library folder and tried deleting some prefs I thought might be the culprits but I've had no luck so far, any assistance would be appreciated. I use OS X on a G4 cube, 256 RAM. Thank you
