Nesting groupboxes: weird results

General
1

Hello

I try to nest 2 groupboxes, I didn’t change any of the settings of the nested groupbox, but it gives weird results:

As you can see, the font is bigger, its bold. But that’s not why I set in the properties of that groupbox.
What do I do wrong?

Thanks

It’s an old problem. Recent discussion here. Feedback 10431 (there may be others).

Thanks. Me.Parent = Nil in the open event of the nested groupbox works.
