Edward:
I tried the Lockscreen property but the effect is still happening, the strange thing that this is only happening when using the page up and page down keys, I will try to trap for these keys in th grid's gotfocus and lostfocus event to prevent these keys from beeing used. I think is a VFP bug that I have to live with. Thanks a lot for your help!
