Thanks for the crash report. It looks like something is going wrong inside the graphics or GUI binding (again), where an incorrect argument is supplied to a library function. Unfortunately, I can't tell from the crash report which function or what sort of incorrect argument. You could try the latest release, v5.1.1, but I'm not optimistic (in part because it didn't help last time). A core file might give me enough information to make progress. Can you try running with core dump enabled, so that a file is written to "/cores" that you could send to me? http://developer.apple.com/library/mac/technotes/tn2004/tn2124.html#SECCOREDUMPS Thanks, Matthew _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
