Roll your mouse over the 2nd vertical rectangle "Avtron Industrial Automation". You will see another layer that shows with 2 other image rollovers (Drives & Systems, Encoders). Move your mouse over both of these links and you will see our problem. There is a flicker back to the original state of the first image as the mouse moves on and off these 2 image rollovers.
We need to get rid of this flickering between layers. You can see the html by viewing the source of this page. You will also find a link to the css there too.
