Thanks for the pointer, Paul. Unfortunately that doesn't seem to be the solution. I removed the "T", opened a script, ran it to check it worked and that was fine, but if I introduced an error I got the same "exception_handler.pm" error, and not the usual useful Perl error messages.

I might try a perl newsgroup.
