If an menu was used as a drop-down from a vbAccelerator Toolbar control, and it contained infrequently used items which were hidden, once the items were exposed they did not respond when clicked. Now all items click correctly.
When showing as a chevron in a menu, if you customised which buttons were visible they could incorrectly appear in the chevron menu.
Disabled items now draw in the correct colour when XP style is in effect.
