ActiveX form and ShowHint property

    Last year I wrote an active form in Delph 3 running on NT4 sp3. I was
asked to modify the control to display one extra field. Since there is no
room on the active form I decided to use the hinting feature. When I enabled
the ShowHint property the active form became unstable. I added no code to
the form (set the hint text and enabled the ShowHint). When I diabled
ShowHint the control became stable again. Has anyone else seen this problem?

Thank's in advance for an ideas you may have...
