Hi Guys,
I created MDI parent form, and create one MDI child form. When I try to change ChildForm:Visible status to FALSE or just ChildForm:Hide() and then change the
status back to ChildForm:Visible = true or ChildForm:Show() I lose the focus. I tried to use Activate() / Focus () and it doesn't help. + After I hide/show the child form,
the behaviour of maximization of the child form changes. What can I do and what's the best practice to hide/show child forms?

Thank you!
