I have a form, with a pageframe with Tabs set to .F. and pagecount=14

On page1 I have 6 buttons and 1 label that conditionally sets visible to .T. or .F. depending on different criteria.

This all works just fine in development without any problems. When I compile my .EXE and test it on various workstations these buttons and 1 label that should be visible are missing. However if you move the mouse over where the button should be, they magically reappear. This only happens randomly and only on certain machines (XP and Vista both).

There is no code in the mouseover event of the buttons. These are just simple buttons, each with a call to a form method in the click event. That's it. There is one method on the form, called by the form's refresh() that conditionally determines the visibility of these 6 buttons and 1 label. I have verified that lockscreen is set to .F.

And this problem can NOT be reproduced in the development environment. It only happens in the compiled EXE... and only randomly.

So................ any ideas?
