Since Executor doesn't emulate the FPU, trying to use it will cause a crash. FPU-less Macs also die this way (although I haven't tried IntelliDraw). Sometimes programs that die wind up executing garbage code which happens to look like an FPU call, so this can be misleading. You should check the IntelliDraw documentation and see if it requires an FPU. I've heard there's a software FPU init (or something like that) for the Mac that we might be able to get running under Executor. That would be easier than actually emulating the FPU (which isn't _that_ hard). -Mat
