Hi there,
This is an issue with ASP.NET and IE 8. Take a look here for more details:
IE8 and the Menu
There's a work around available, as well as a fix you need to apply to your server.
Can you please post book related messages in the book's forum at
http://p2p.wrox.com/book-beginning-a...0-18759-3-389/ instead of this general ASP.NET forum? Makes it easier for me and others to track messages.
Cheers,
Imar
