I've been spending a few weeks adding image galleries to my website using this code: http://www.cssplay.co.uk/menu/slide_show.html However, in IE the larger image only opens when I click a slide, and then move my mouse off of it. Why on earth do I have to move the mouse off of it for it to to open? This is currently driving me nuts. Why is it working on that site, but not on mine? As far as I can recall, I didn't change much of anything. Here are the problem pages: http://bonaweiss.atspace.com/cythera/MAIN_menu.html The css file for Firefox is here: http://bonaweiss.atspace.com/cythera/slide_show.css and the css file for Internet Explorer is here: http://bonaweiss.atspace.com/cythera/slide_show_ie.css Thanks in advance for any help offered. EDIT: and the answer from Stu himself:
