Hi, I'm using 10.2 and have a couple observations (requests?):

1) If NavigationAllowHide property is set to False, then the "Navigation Pane Options" dialog's group checkboxes cannot be clicked (ok), but they appear enabled (not ok). i.e. not the usual grayed out disabled appearance.

2) If NavigationOverflowButtonAreaVisible property is set to False, then the entire overflow area is hidden (ok), but the navigation splitter can still be dragged down to hide all the groups (not ok). There should be a way to either hide the navigation splitter, disable it, or at least have it automatically disabled if the overflow area is set invisible.

Thanks, Les
