If you are using in the same page different libraries like jQuery and
MooTools, there are high changes that you'll have a big headache, and
you should just forget about it. Stick to one library, avoid adding
new libraries to the mix because some of them modify some internal
behaviors that are quite difficult to understand at a simple gaze, and
then the other library will try to also do its changes and now it
depends on how lucky you are.
I think that currently the libraries are trying to avoid these
problems, but if you are forced to use older versions, then it will be
hard to fix the problem by yourself.
