Totally guessing, but perhaps it's a ROM update specific to the A1200? Or perhaps it's something else. I was thinking about writing a showexecute CLI command that basically would write out the line it's going to execute before executing it. It would help trouble shoot issues like these. It could also log a file to a RAD drive or something or any non-FFS drive; wouldn't want it to crash during a write and invalidate the disk; I swear FFS likes to invalidate itself if you just look at it funny.
