The items of RadRotator are not rotated correctly when the FrameDuration property is set to a small value and the PauseOnMouseOver property is set to true.

When 'FrameDuration' is set with small value, for example 1, the rotator will not be paused on mouse over even if 'PauseOnMouseOver' is set to 'true'.

Currently the RadRotator is not displayed under mobile Chrome for iOS.

The issue could be worked around by switching Chrome to "request desktop site" mode from the browser menu.
 

If a RadRotator is set in AutomaticAdvance mode and its property PauseOnMouseOver is set to true, it will start scrolling incorrectly when the cursor is moved over the items in the scroll direction before the scrolling is completed.

drag with easing and inertia.  It would be nice if you could drag and throw the items and they would speed up or slow down based on the strength of the throw.
