HP-41CX w/ XF-Module - just curious

Very true, but again it's very unlikely that another ROM with id#25 AND fewer functions than the CX/X-Functs is present, right?
If it were, the user wouldn't have access to any of the X-Functs above that number, which is more dramatic perhaps.

So I'd call this a "benign bug: the OS doesn't find your target and then offers you a "consolation prize" ;-D
