We have a customer who is using our application and on quite a frequent basic the screen goes blank, then the blue screen od death appears, most times the customer has to turn off her computer. It's only happening when they are using our application which is developed in VFP7 sp1 I have deleted the foxuser files. It can happen anywhere in the program so I don't think it's the printer driver. Could if be the dispay driver their computer is running Windows ME and the driver is for a nvidia gforce2 MX/MX400 the driver is nvdisp.drv version 4.13.01.30082

The problem also orroured when they were using the app developed in VFP6.

Any ideas would be greatly appreciated.
