>We have a visual class-form from which, after having run a recursive method (any recursive method), all the objects disappear when the mouse-pointer gets moved above any of the buttons on that form. Only when resizing the form, the controls regain visibility. Even more, the problem doesn't occur any more.
>Only when closing this form, re-opening it and doing exactly the same, the problem shows up again.
>When we disable the XP-theme for the buttons only, the problem is solved.
>We tried altering the style of the buttons from 3-D to plain, same problem.
