changing theme name breaks layout?

Issue Summary

I like this theme (thanx for your work) and wanted to use several versions of it on one site along with switchtheme module for users to toggle between them, but whenever I rename this theme's folder from "internet_services" to anything else (e.g., internet_services_1 or whatever), the layout breaks.

Specifically, the primary menu items no longer appear as highlighted rectangles horizontally placed in the header, but instead appear as a long, vertical bulleted list in the header.

I went into template.php and noticed several theme specific functions, meaning that a users can't simply rename the folder but has to edit code as I thought was kinda common Drupal practice?

Problem is that when I did a global search-replace for the theme name in template.php (2 occurances), i got the primary links menu to display twice, stacked on top of eachother in the header-- one as the bulleted list, and then once below that as the intended horizontal/highlighted recatangles. I couldn't find any other references to the theme name in other files, so not sure where else to look.

Two questions:

• Is it possible to rework this template to be more generic/forgiving of name changes, and/or
• What other code do I have to change to get the primary menu links to only display once?

Thanks again-- nice theme and hope to be able to use it.
