Hi Dale,
Do you have any other modules that are loading any type of script along with the page? Have you placed custom .js links in your default.aspx or in the "Edit Page > Header" section?
In your host settings, do you have jquery enabled?
The issue seems to be pointing to a script conflict of some sort... unless I'm completely missing the obvious.
To narrow down the issue.. Is everything stripped clean from that page? Additional css? jquery? Java? etc?
