It may be differences with Javascript - in IE5 if you go to tools - internet options - security - custom level (each of these is a menu choice) and then disable active scripting it may remove some funnies (I havnt got Netscape installed on this machine so can't test but think has similar options). Personally I always browse with high security settings switched on with images disabled (many sites hide annoying popups, ads, cookies etc within
images - you can always right click on specific images to view).

If others are having problem maybe posting details of which browser they are using, might help admin debug funnies - the page layout appears to be derived from http://www.milonic.co.uk/menu/ which site mentions some funnies with Mac Safari browsers
