I'm having the same problem (OS 9.04, G3, 17). I've tried following the advice here re: resetting the port # in options, but the program won't accept the change -- it freezes every time. Except when I disconnect from the net first, in which case it reconnects me when I hit the apply or ok buttons, and =then= freezes.

Anybody else seeing this? If so, how did you fix it?
