It's VFP limitation that objects should not be placed beyond the coordinates (video resolution * 2 - object height or width) in a form. See BUG: Scrollbars Disappear if Objects Placed Past Certain Length mskb #Q216985.

>Hello,

>I'm having a problem for which I can't find a solution.
>
>I activate a vertical scroll bar in my form.
>Now I add object in my form (A textbox, for example).
>If the Object falls out of the Forms Viewport, then the scroll bar get visible and I can scroll the view port dow to see the object.
>
>Now if I set the TOP Property of the object to 1800, I can't scroll down enough to see the object. It seems I can only scroll down to the position 1710 (or so)
>But this is because I'm using 1152x864 screen resolution.
>
>If I change the screen resolution to 800x600, then I can't scroll to a position higher than some 1300.
>
>This behaviour can be seen in run-time as well as in design time.
>
>What is hapening here ? Is there a limit for the scroll of a form ?
>Isn't there any workaround ?

>Thank you for your help.
