I what way is this comforting? Does it just not like my browser? Don't ask me.
Update: Okay, I tried it on another machine, and it works there. So it doesn't like my browser!. I then used Rex Swain's cool HTTP View tool to see what was going on. I tried it from the working machine and saw a very different UA string. So I tried removing elements one-by-one to see what made it work. Eventually, I had removed most of the non-standard stuff (.Net CLR versions, etc.) and got it to work. Once I got it to work, I added the missing bits back one-by-one. It's not which strings are in there, it's how long the UA string is.
This is pathetic!
You don't let people see your site because their UA string is too long?
