Thanks for the help, but since I'm no longer on maintenance, when I
follow the link you provided I'm not allowed to download anything! Can
you provide me a way to get this patch?
Let me check and see what I can do.
I will let you know.
When you go to the Download page you should see a Patch Request Exception Form for customers without support. Fill this out and we will send you the patch.
