I don't have VFP 9, but I seem to recall recommendations to disable themes as a standard attempt to resolve problems like this.

>I have a problem with some very (very very) old foxpro code. The following code I want to run with VFP 9.0 (SP1). When running it will show a small window with some text and a button. When moving over the OK button all the objects on the window will be invisible! When I remove the [*] it shows the text, but there will be no button!
