I've occasionally seen a Java.lang.stackOverflowError but most often it freezes up and then the next click causes it to crash with an access violation. Linux behaves well until it gets beyond 600 and then also starts to freeze up (doesn't seem to crash). I haven't dug into what's going on under the hood.

We might want to consider imposing a limit on Linux and Windows, too. It could probably be done as a follow-up...
