Tabstrip not rendering...

[DalePres]

I have an application that uses the Microsoft.Web.UI.WebControls.TabStrip
and Multipage controls. When I test the app on my pc or on my client's
development web servers the controls render properly. When I deploy the app
to the test environment - supposedly an exact duplicate of the development
environment - the TabStrip and Multipage controls do not render - the text
of the tabs are displayed in a line, but no tabs.

This is the same behavior I get if the .htc files are missing but I am
certain they are there. In fact, if I manually enter the address for the
..htc files in my browser and download the files to my desktop - thereby
leaving a copy in my Temporary Internet Files and proving the files exist
and that I have permission to get to them - then the controls will render
properly.

Other .htc files associated with the same pages and with the application all
work properly. When I look at the rendered source code, the address given
in the reference to the htc files is correct.

Does anyone have any experience or knowledge about this?

Any help would be greatly appreciated!!
