We have a RadRotator that is inside of an iframe and we also have a context menu on the rotator (inside of the iframe). When you right click on the rotator, the menu shows up fine. However, as soon as you manually rotate the rotator to the next panel, the menu starts to appear entirely white. We had this problem with the 2008 controls and we were told to place this CSS change into the page:
This worked just fine with those controls, but now for some reason it no longer seems to do the trick with the latest and greatest version. The output of the menu appears to be very much the same as it used to be and I verified that the CSS classes exist with the new version of the controls.
