Just to let you know that you're not alone.
Crashes started after installing LW X 3.7.x and continues with version 3.8.2.
Installation proceeds fine, customizing prefs goes fine, thenit crashes, and crashes on every launch attempt.
Running Panther 10.3.2 on a Dual 2 gig G5 with 1 gig ram.
Hope there's an answer or fix soon.
