Went ahead and uninstalled Firefox 3 and installed Firefox 2. Solved those earlier errors but now I get all of the old X11 driver errors and the resulting poor interface in Firefox (no icons, etc.). More alarmingly, for the first time in all of my various Wine builds I'm having WineHelper hang and having to use the "Force Quit" to clear the problem. Another possible symptom is I tried to install one of the programs I had on my earlier Darwine build and now it won't install. The last time I installed it (on the kronenburg 1.0 build) it installed in 5 minutes with no errors. Now all I get is errors and a hang. Do I have a problem with this Darwine build or is this normal? bob wine: Unhandled page fault on read access to 0xffffffff at address 0x1017:0x00000c1d (thread 001a), starting debugger... couldn't load main module (2) Unhandled exception: page fault on read access to 0xffffffff in 32-bit code (1017:00000c1d).
