As you can see on this test page, hovering over any item in the menu causes the entire menu to flash white before the submenu appears. I only see this on IE installs with standalone IE6. On my machines with multiple IE installs, everything is fine.
Oddly, this does not seem to happen if I go to another site and the arrow back to the test page. If I refresh the page though, the flicker comes back. I'm using background image positioning on hover rather than image swapping, so I don't think it could be an image caching issue, and I'm confused by the fact that it's the ENTIRE menu that flashes and not just the element that is hovered over. I don't see the same behavior on the examples at the Superfish site, but I am using background images rather than background colors, so I suppose I could have screwed something up in that process. Any help at all is greatly appreciated! Test page: http://extranets.beaconfire.us/superfish-test/ Cheers, Tim
