[jQuery] Superfish - Entire menu flickers on hover

[jQuery] Superfish - Entire menu flickers on hover


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!
