This is not a bug within Netscape or other Mozilla based browsers. It is a fact a known bug within
the JavaScript coding of all retail websites run by the Dixons Retail Group, not just Dixons.co.uk.
The websites of Currys.co.uk, TheLink.co.uk and PCWorld.co.uk are also affected by this issue.
There is an existing Tech Evangelism bug
(#88596) filed at BugZilla regarding this problem,
Until the Dixons Retail Group actually get around to fixing their broken JavaScript menus, then I
would suggest you take the money you want to spend, to one of Dixons' rivals, such as Comet.
BTW . . . The aforementioned Tech Evangelism bug was on the 30th June . . . in 2001!
