Dominique,
I still see that issue … your background seems to super impose when mouseovering the links .. but only for a split seconf.
It’s pretty easy to reproduce by mouseing over the left hand menu – and then taking the mouse to the main menu in the middle of the page.
(repeat a few times if it doesn’t happen immeidately)
It is very distracting – I’ve tried a quick look at the source – but there is quite a lot of sourcing in of seperate javascript routines – and impossible to diagnose base on script names.
However, this does not look to be any sort of hi-jacking or redirection … rather it seems to be some sort of javascript control on mousing the links.
I’d say the issue is faulty coding.
