I have a problem whereby when I launch my app from the emulator shell i get 'STOP! SYSTEM ERROR'. There is no error number associated with it (yes, emulator is set for extended error mode). My application never actually gets to the point of displaying anything.

I've not been able to isolate the problem as yet and wondered whether enabling JIT debugging might help but thats my problem, I don't understand how to use it!

If i turn JIT on and launch my app in the debugger a Halt is executed almost immediately, again, I don't really know how to use this information. Could anyone give me a few tips?

I'm using Express and Series 60 2nd Ed FP2.
