Andreas,

Do any of your forms have the LockScreen property set to .T.?

>I have a form with lots of controls but no shapes (VFP6)! Sometimes especially on slow machines when
>a form is shown (overlapping other forms) some transparent areas occur (which show the forms behind).
>Clicking on the form below and again on the top form resolves the problem. This happens only from time to time.
>Any suggestions. Thanks.
