I created a simple MDI Program giving the main form and the child form a standard file menu. In order to ensure the merging of these menus I set the MergeType property to MergeItems. Each of the file menus has a handler attachted on the popup event. Every thing works fine for the main form without a child form opened. When I create a child form at run time non of the two popup handlers is called. I would expect that at least one of the handlers is called.
