You either have _screen.lockscreen = .t. or thisform.lockscreen = .t. on. Change them to .f.

>Hello,
>We are using VFP 6.0 and we open Forms from other Forms by using dblClick in a grid for example.
>If the new Form is moved over the other Form, it happens that the underlying Form is overwritten by a kind of delay picture, and no longer readable. However, when clicking on the underlying Form, it is clear again, the the effect does not occur, unless a new Form is opened afresh above another.
>This is not really an error, but not very nice either.
>Knows anyone about this effect, and how to avoid this?
