HELP !!! GPFs in PowerBuilder 4.X using INFORMIX

HELP ! We are getting TONS of GPFs using Powerbuilder 4.0 with Informix version 7.X running on an HP 9000. We are using Informix's native middleware INET. What versions of everything should we be using ? Are others having same problem ? What are some workarounds ? Here is one of the GPFs we get: Application Error caused GPF in PBDTP040.dll at memory address 0003:0FAC We simply performed some sql via the admin icon on a table, then shut the windows down and tried to bring up a different table (or the same one again) and got this error. It happens like clock work and prevents us from doing much at all. We have to reboot and start all over again each time. Any help greatly appreciated. root@TeamInfinity.com
