Hi Max,

I think it's Windows limitation (it exists in VB.Net and C# also). You've a few alternatives:
- Put your own WhatThis button on your form with following code in the click event Thisform.WhatsThisMode()
- Use ToolTips
- Use Right-Click WhatThis menu, as it's done in VFP itself and other MS applications.
