Upgrading Jquery breaks everything

Upgrading Jquery breaks everything

So I created a mobile app with dreamweaver CS5.5, which used the jquerymobile 1.0a3rc and jquery 1.5.
The app has a lot of javascript functions, buttons, etc, and works fine.
Any attempt to update it (jquerymobile 1.0/jquery 1.64 or any newer version) results in none of the functions/buttons working, but also NO LINKS work period (even the list item <ahref="#">.

Any idea what could be causing this?

I've tried a variety of things, like removing the javascript buttons from the page, and then the regular <ahref="#"> links function again.  So I would assume there is something about the javascript or the buttons...

Too much code to post, but most of the scripts are in the head and are called via input buttons or linked buttons.

Thanks for any guidance you might have
