We recently upgraded from the Q2 2008 release to the Q2 SP2 release. In one instance, we have a radrotator with a context menu that is inside of an iframe. When you right click on the rotator the menu attempts to display, but displays as all white. and covers up anything in the rotator. This was working in the original Q2 release.
The menu is using the Default skin and has 4 items in it. If I run the page that is normally inside the iframe outside of the iframe, the menu renders correctly. In both instances, I can click on the menu (even though I can't see it in the iframe) and it will respond correctly.
