I did another search of WP.org to see if anyone else has had similar problems. None reported. So, I decided there might well have been a problem during install. I reinstalled 2.7 and no longer have the problem. Thanks for your help MichaelH.

@michaelh: Thank you for the suggestion. I have the same problem when all the plugins are deactivated: the admin panel menu items work as expected EXCEPT for the two cases I mention above.

I also tested the domain settings, as my wp install is domain.com/blog but the blog address I use is domain.com. I still get the 404. The tool menu items point to /blog/wp-admin/tools.php, which is correct. So why the 404?

All other menu items work as expected in the admin panel. Any suggestions are most appreciated.
