Does this have anything to do with the changes to MSDN (which I'm not sure I like either)?
Apparently yes.
Basically, what they did was replace the HTML help from previous versions of VS completely. Now, it appears that you have two choices... the familiar old standby of "Online" help through MSDN, or a "local" version of MSDN. When I say local version, what I mean is that it installs what's called the "Help Manager Component", which is essentially a localhost web server. You download help repositories (you choose which ones though), then once installed your local help consists of spawning your default browser and connecting to your localhost "help" web server. It behaves very similarly to MSDN. In fact, because you mentioned it I took a look, and yes - it is almost IDENTICAL to the online MSDN library now. No index, no filters, just a category-based TOC and search.
Simply put, it's very difficult to navigate this. If you want to know what local help with VS2010 is like, then yes, just hop on the MSDN Library online.
