I hope this helps, SLH.

The problem is a defect in the MDI management code inside Windows itself; you will end up with various menu problems if you do it this way. At the moment, the safest way to get maximized MDI children is to 1) Use SetRedraw(FALSE) to turn off updating of either the main frame window or the MDI client window. 2) Create the new MDI child normally. 3) Maximize the new child. 4) Turn updating back on with SetRedraw(). 5) Invalidate whatever needs to be repainted.
