I have a problem with IE6 and jquery slider. Please click on the following link than click on the button "dodaj u košaricu" on the right bottom side. After that click on the "košarica" tab and try to move slider up and down. Some of the elements stay like they have position fixed.
In IE6 all of the elements except table and text stay fixed and in IE7 only the horizontal slider, in FF everything is OK.
