Graemezee, just to verify:
1. The 10.6.3 combo update you are using is 754 MB in size?
2. You are using a 4890 card?
If yes to both then re-run the combo update, once completed reboot. Download and install the proper QE_CI patch. Everything should be back to normal after another reboot.
Hi Treksdot yes to all your questions, but got your later post and applied the fix for a fix and everything perfect again Thanks for your efforts.
