ie7 is messing up my image placement (and dropdown menu)

Hi guys,

This is an internet explorer 7 specific question. If I view this test website: here in ie7 there are 2 big problems that mess up what happens.

#1. The images move on hover.
– The header image shifts
– On the page “profiel” the image in the text moves to the left and presses against the text once your hover over it.

The images should be static, obviously, but ie7 doesn’t listen to me.

#2. The dropdown menu (under profiel) li’s are on top of each other instead below each other.

I have spent many hours trying to figure out why this is going wrong! Please help me, any suggestions are appreciated!

Thanks!
