Forms 4.5 GPFs continually - HELP!

HELP! I am using Forms 4.5 running on a PC against an Oracle 7.1.6 database on  a DG Avion. The problem I am experiencing is that when moving from form to form at runtime, I repeatedly encounter a GPF:

GPF in TK21WIN.DLL at 0012:0BF5

This is by far the most common GPF, but I have also had GPFs in DE15WIN.DLL. In desperation, I have tried:

• keeping no more than one form open at a time and using NEW_FORM() when calling other forms
• completely re-installing Developer/2000 v1.2
• playing with the CONFIG.SYS file to remove EMM386
• running the application on a different PC
• repenting all the sins I can think of

This GPF occurs without fail every time I run the application and move from form to form (and back) a few times.

Any constructive suggestions would be greatly appreciated.
