>FWIW I can duplicate this behaviour. Packing the VCX's doesn't help. I think I've heard of this scenario/behaviour before but can't remember where/when.

Actually packing the VCX's did help, if you can call eliminating the Fatal error a help. This time I get "Error loading form/data environment record number nn."

So I decided to dump the pageframe and use multiple forms instead.
