jQuery UI Tabs w/ ScriptManager and AJAX Mode: Stuck on "Loading..."


I've an issue that I can't seem to figure out. I have an ASP.NET web
page that is acting as a Master Page of sorts (using Master Pages
gives me unintended results). It has the markup for my tabbed menu
and a ScriptManager with some services and scripts.
The tabs are using AJAX Mode to load some other .aspx pages. At
least, I would like them to. When I attempt to load the "Master
Page", I get stuck on the "Loading..." stage in the initial tab. If I
give each .aspx page it's own ScriptManager (with the same scripts and
services) and remove the one in the "Master Page", the pages will load
but not without a "suchandsuch.js has already been loaded" JavaScript
errors.
Is there something I am missing?
