Grrrr... the web.
Just so I don't forget this link, I'm posting it to here. Yes, I'm having to do some web stuff for a project I'm on and it appears that ASP.NET 2.0 "didn't like" the smart navigation feature in previous ASP.NET version(s).

Nonetheless, I came across this document on Microsoft's website outlining how to mimic smart navigation features using other means.
