>I tried to upgrade a application developed in FPW 2.6 to Visual Foxpro 9.
>Everything looks good until I move the mouse anywhere on the migrated forms. All controls disappears. If I move the mouse pointer over a button, it reappears. Next time I move the mouse pointer over the same button again, it disappears again.

>This strange things only happen, when the property _screen.themes =.T.
>After changing the setting to .F., everything works well, but it looks not very well.

>You can see the same behavior in VFP 8.

>Now my Question: Will this bug be solved in the final version of VFP 9 ?
