The source in the vcxes is inside the exes, for prgs, however, only the fxp is in there. It works on your machine because the physical prg file is still on the disk - try to do this with prg renamed (or its folder renamed) and you shouldn't see the source in the debugger on your machine either.

If you want to see it on the other machine, bring the source over, on the same relative path to where exe is run.
