I used to use a Program called (From memory) "NO GURU"
I was great if something crashed the Amiga would bring up a large requester giving me lots of details... and several options, like Continue, Freeze, Kill, Save Log and Cancel...
I had it set by default to save to a log file, where it gave a full debug info of the CPU regs and stuff like that... The Freeze feature was great, as you could lock the program and continue using your Amiga, for some reason Killing the program, would just case a reset :-/
