[AccessD] Naming subform control causes page fault

I have a pretty strange one at a client.  They have a form with ~10 tabs, each tab has one or more 
subforms.  If I try and drag and drop a new subform onto a new tab Access page faults when I try to 
save the subform.  If I drag a new subform CONTROL onto the tab I can save it, but if I then try to 
name the subform control (change the name) it page faults when I try to save.
