I don't know whether the problem is MINE or THEIRS, but I found a cheesy work around that allowed me to do my dog-&-pony show today with grace, aplomb and no GPFs or Dr.Watsons. Who knows, I may just leave the cheesy work around in place.

Can you be more specific about the problem and your work around. We are also using MaxFrame. I would really appreciate it.
