Has anyone else encountered problems with javascript that was working fine in XWD7 but now will not work or is acting funky?

I had several different bits of code in placeholders in my XWD7 site and after I updated to the new MX version, some of these went haywire.

Specifically:

on page load popup
add this-widget
Cloud Tint Zoom Gallery
(funny thing with this is that I have three instances of this gallery on the page and only one went nuts)
