I deleted limewire prefs, deleted app folder, emptied incomplete folder and reinstalled pro version 4.0.3 and it's still crashing. as far as i can tell - from the console log - when LW crashes I see these in the crash log...
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000048
and.....
Thread 1 Crashed:
0 com.apple.CoreGraphics 0x936218a4 CGFontGetUseIntegerAdvances

i have no idea how to read or interpret these new logs on OS X so this is about all that i could see that was a cause of the crash(??!!)

i'm about to start in safe mode and see what happens... will let you know... i haven't heard back from LW support yet to get their take on it so i appreciate the help 8-)
