We have one client that VFP is losing the modal status of forms. We are based on AccPac and in their code they have a

DO WHILE TYPE(gc_frmname + ".BaseClass") = "C"
  &gc_frmname..SHOW()
ENDDO

Initally the form is loaded the WindowType is 1 (Modal). Every once and awhile the screen will just start flashing and I dial in and check and the WindowType is then set to 0 (modeless). It's never constant and we don't have anywhere where we are messing with the WindowType. The other strange thing is that they also lose the form object reference. In the same statement above where we check to make sure the BaseClass type is "C" before we do the show it says "Object xxxxx is not found."

This is only happening on one client of our the rest run fine. I've talked to their network guy and he said the way they have the network setup is weird but I don't know if the network could be causing any of this. Any ideas?

Thanks
