The thread on the Perl Portal (web app) site seems to be where Alatar is coming from. Through that it works fine in versions before 5.8.1 . I have to get a train but the only comment I can say after downloading and reading the code, is very little comments, all vars are global and no strict, it hurts the head to swim through. I will pick this up at home though because it is not IE and anything that has me not tracing problem in IE is a good train of thought.

Update I would have to believe that simonm is right. The lock subroutine should be renamed and using a search and replace utility rename all calls to the sub also.
