Nice design, shame it doesn’t work properly
It still amazes me how many well known web sites have general usability problems that effect their ease of use. The latest I came across was ironically the London Design Museum website.
The index page looks quite nice, as you would expect from a site exhibiting and promoting good design, but it’s when you actually get beyond this that things start to go wrong. The main problem on both flash and html versions is the menu that appears when you rollover the shaded bar on the bottom of the new popup window interface. It seems to work sometimes and disappear on other occasions creating a frustrating environment for the user.
Another issue that may be more of a personal dislike is the switching between several browser windows whilst interacting with the site.
