I am not saving as runtime or droplet only as plain text from MacPerl
editor then running by typing shift-command-R (runs script in frontmost
window). Viewing the debugger and output I can tell the wrong version (that
no longer exists anywhere I have saved it) is running. Occasionally the
correct version will execute but it sure is lengthening the development
process :-) This occurs >95% of the time.

Did you develop a solution around your problem? (this is version 5.0.7r1m)
