After the first rollover, all of the top tier menu items shift a little to the right. Then they stay put and don't move again. From the user point of the shift is very noticeable. The effect is the same as an image that is placed on a page without width and height attributes. When it loads, it jumps.
I have tried both standard skins as well as custom skins. Same problem.
Any help would be great
I tried to post a sample of the code in this forum, but the script gets altered.
You can download the sample from here
