I have an CMFCRibbonCategory that contains three CMFCRibbonPanels. The first of the three always appears in a collapsed state (just the panel name and icon as a drop-down button), even if enough horizontal space exists in the ribbon bar to display all three
panels fully. This occurs on WIndows 7 when text magnification is set to 150%, but not when set to 100%.
What could be causing this, and how do I achieve the desired (and purported by Microsoft) behavior: display all panels fully so long as there is enough space to do so?
