I thought it was about time I upgraded my driver for the old 9500 Pro, so I
completely uninstalled the old one (6.4) and installed the latest:
8-12_xp32_dd_ccc_wdm_enu_72271
All was fine to begin with but upon rebooting it no longer remembers the
resolution settings and reverts to 1024x768

I've done a search but can't see a reason for this, any suggestions are
welcome.

Regards,
Gary
