Some other people tried this sample and they also got c5 error.
What I can do to eliminate this error ?

>I see what you are saying. I mistook the repetitive F3 for an error. You're right I cannot reproduce the c5 error. When I let it run, it continues until finally stopping on a client name. I can scroll to other clients, etc. However, if I access the task manager (W2k sp2) it causes an 'invalid seek offset' error in your app. I don't have to click on 'end task', only bring up the task manager to cause the error. If I access it during the F3 cycle it errors immediately. If I access it after it stops, when I try to change records on the grid, it causes the error. It's also interesting that the error causes my instance of VFP7 to lock up (it doesn't lock up VFP6).
