FIX: No Menu Event with Maximized MDI Child

SYMPTOMS

A top level menu's click event on an MDI form isn't fired as it should be when the MDI child is maximized and a sub-menu item exists for that top level menu. There is no click event generated regardless of whether the menu is part of the MDI child or the MDI parent.

STATUS

Microsoft has confirmed this to be a bug in both the Standard and Professional Editions of Microsoft Visual Basic version 2.0 for Windows. This problem was corrected in Microsoft Visual Basic version 3.0 for Windows.
