Elementary problem -- pages lacking URLs

Hello everyone. I'm just starting out with Movable Type and have run into a problem that I suspect has an elementary solution, but one I haven't been able to find so far.

While playing around with MT (I'm debating converting my entire website to MT but want to get a better sense how it works first) I've got it set up at http://www.domain.com/blog/. I've been able to set up a blog within my MT install and publish posts just fine. I've also been able to create Pages inside the blog that work fine.

But where I'm running into difficulty is trying to set up Pages within the MT website's top level -- a "resume" page, a "personal" page, etc. I'm using the Professional Website and Professional Blog themes (though I'll probably start customizing them once I get problems like this ironed out). I'm able to create and format those pages just fine on my dashboard, pick a filename, and press publish.

This is where things go wrong -- the pages I create are never assigned URLs. At the top of the editing page it gives me the permalink for each Page: "http://www.domain.com/blog/".

When I publish it and view my site, all the Pages I've given the @navbar tag to appear as links in the navbar. But other than the first link, to "Blogs," none of them go anywhere. They all link to "http://www.domain.com/blog/" -- the page I'm already on.

The only one that works at all is the home.html file with the welcome text. That shows up just fine in the main body area, in the left column, like it's supposed to. But none of the navbar links work, and indeed, going into my webspace via FTP, the HTML files don't exist. I can still click on them and edit them in my Dashboard, but they don't exist as HTML files.

I've tried putting Pages in folders and at the top level.

Interestingly, the FP server does contain the original about.html file -- despite the fact that I edited about.html in the Dashboard and put in other content. The file on the server has the lorum ipsum dolor text; the one on my Dashboard has my text but doesn't exist on the server.

Again, I suspect I've done something rather basic incorrect here. Does anyone know what I need to do to get this to work?

Thanks.
