ATI 9700 Pro Problem

Hi,
I’m looking for advice regarding what looks like an incompatibility problem with a customer’s ATI 9700 Pro and our product.

Unfortunately, we haven’t got access to such a card but our application is causing a fairly random series of problems :

  1. Program loads … display drawn followed by a complete system lockup needing a reboot.

  2. Runs but all texturing that uses glTexSubImage2D is corrupt … usually crashes but after a while.

We gave the usual response that normally does fix problems … ‘Update your driver’.

The customer is running XP and is using Catalyst 3.2.

Any ideas ?

Andrew
