How to fix "unsupported browser" errors when using IE7

Some sites attempt to check the browser version and get rather confused if IE>6. If you are evalating IE7 Beta then a good tip is to add the following registry entry - bear in mind this is unsupported but I presume the Beta software is too so nothing lost:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent]

"Version"="MSIE 6.0"
