Hi,

I found a bug of XamRibbon with sub items (e.g. RibbonTabItem).

For example, I have 3 tabs, Format (O), Insert (I), Font Section (JS), and make Format tab visible by default.

Steps:

1. press Alt so that short cuts of tabs shows up;

2. press I to switch to Insert tab;

3. click the tab header of Format to switch back to Format tab;

4. now if you click on Insert tab, nothing will happen, it will not switch to Insert until waiting for a while or changing the visual elements (if you minimize the app or make the ribbon hidden, then everything goes back).

Is it a known issue? are there any solutions or workaround plz?

Thanks for help.

Nathan.
