in reply to PP - am I crazy or what!?

How did the installation of PAR go (did all the tests pass)? Which version of Tk do you have? Can you share rgp.pl (or do you have a minimal test case)? You should contact the authors of PAR.

update: I did experience some issues with the latest version of Tk (Tk804.025_beta2), so it may be related somehow (just guessing).
