The problem happens when setting max-width to all Rotator divs using a weak CSS selector:
			.RadRotator div {
				max-width: 800px;
			}

It is strongly advised to avoid using such selectors for the controls, as they may break the rendering and functionality (as is the current case). The workaround it to make sure that only DIVs outside the control have been affected by this CSS rule.

When the RadRotator is set with the Sitefinity built-in skin and it is configured in a mode with buttons, the buttons are not displayed.
You can workaround the problem by adding the following CSS code on the page with the rotator:

<style type="text/css">
    div.RadRotator_Sitefinity .rrButton.rrButtonRight {
        right: 0;
    }
 
    div.RadRotator_Sitefinity .rrButton.rrButtonLeft {
        left: 0;
    }
</style>

I don't ever use the radrotator because of how dated it is....sets a fixed with (rrClipRegion), rotated items flow behind that, jquery based animation...etc etc.

Can we please knock this out of the park and make something like http://dimsemenov.com/plugins/royal-slider/

Look, if you guys didn't use your own rotator on the new telerik.com....something needs fixing, no?  #Dogfooding

It will be possible to specify an ItemTemplate for RadRotator that loads its items on demand.

It would be nice to give Rotator the ability to refresh contents every x minutes or seconds right out of the box, providing a refresh interval option. This could only work when using webservices, page methods or any other data fetching method, as long as it existed :) This feature is very useful when data needs to be refresh without user intervention.

An exception will be thrown when there is a a standard ImageButton or a standard Button with UseSubmitBehavior="true" in the ItemTemplate of a RadRotator and it triggers a postback.
