focus problem with multiple forms

[Steven]

Hello,

I have an application with multiple forms. I open 2 (different) forms,
one with numerous controls, say A, and one with a MonthCalendar, a
Combobox and a datagrid, say B.

When I work in A, but B is also open, sometimes A is set behind, and B
appears on top of A. Amazingly, B doesn't get the focus, the focus is
still in A. It's just that B appears on top of A (B's menubalk is still
gray).

Anyone familiar with this problem (and the solution) ?

I think that the MonthCalendar is to blame, but i'm not sure.

Thanks,

Steven
