jQuery fancybox '*.support not defined' or 'b.support not defined' Error

I was trying to use the jQuery plugin fancybox today. I followed all the instructions but kept getting this error:

*.support not defined

When I used the packed version of fancybox, I got this error:

b.support not defined

After pulling my hair out, searching Google and still not finding any answers, I decided to use a different version of jquery.js. That worked!

Apparently, the version of jquery.js that I was using was an incompatible (maybe old?) version. I finally used the version from here:

http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js

Maybe the next person who makes the same stupid mistake will find the answer much quicker than I did!
