Thanks for your comments!
We decided to rework the focus behavior of the RadToolBar
in a manner, that will avoid the visual glitch. Let me explain:
The problem happens, because we use similar look for focused and hovered items. When a button get clicked it stays focused until the user clicks somewhere else on the page. We discussed two possible solutions - either to change the look of the focused item, or not to apply the focused style when a mouse click happens.
We chose the second option - when navigating through the keyboard the focused style will be used, but if the mouse used, only the hover style will be used.
We are working on fixing the behavior for the first service pack of the suite. Let me know if the time is critical for any of you so that we can prepare an unofficial build once the fix is ready.
