The problem appears to occur when you don't give it enough memory; I was able to reproduce this under Linux with: executor -applzone 1400 So I went over to a Mac and edited the LemmingsDemo SIZE resource so it only gets 1.4M of RAM (which Lemmins says should be enough). Lo and behold, it crashes on a real Mac too! So I guess our emulation is accurate. :-) If Lemmings is doing weird things to you, you should be able to work around this problem by saying: executor -applzone 2048 and thereby guaranteeing that Lemmings has 2M of free memory to work with. For our next release we'll probably make the minimum default applzone size be 2M. We've also taken out the 8M upper bound; you can now have applzone and syszone up to 16M! This should make some of you diehard power users happy. Going beyond the 16M limit is difficult because of limitations in the Macintosh memory manager design. -Mat
