[josbvg]

Does anyone know why my pages with this java script naigation jump on load (only in IE after 2 seconds). I am just debating weather its neccesary to replace the naviation to solve this or if ther is a quicker fix.
Any info much appreciated

I'm viewing it under IE7, but I'm not sure if I'm seeing the jump effect.

When does the jump occur? What url? Do I need to click any navigation for it to occur?

Please provide further info.
