We are scheduling the RadRibbonBar control for as major overhaul and will take your considerations into account. Some more information on the first behavior: it is due to the fact that when you execute command on the dropdown/menu of the application button, the focus and mouse capture goes to the popup and thus the activation cycle ("keytip"
functionality) of the RadRibbonBar component is compromised. We are aware of this behavior and will address it when updating the ribbon bar control. As to the second one, it might be connected to the popup also (if you hit ESC
when the popup is opened already). We will investigate it further.
All the best,
the Telerik team
