Yes! i dont use iE! It sucks

but customers do often use that shit...
but i figured out that the problem depended on some strange settings in my iE itself. Switching to defaults in iE fixed the problem - thanx for help anyway

.
But i have another problem with iE7 and the drop down menu - The dropdown menu drops down fine but
the menu which drops down is displaced (only in iE7, iE6 works fine) and its not possible to press the buttons of the headrow any more (i used suckerfish dropdown with some css moddings) but this may be something for a new post....
cheers
