I had to figure out how to upgrade Mootools from Joomla 1.5’s default, horribly outdated 1.11 to 1.2 in order to use some funky scripts in a new client template today, and after a bit of stress and searching I found this:

It seems that the admin dropdown menu’s stop working if you just overwrite the old Mootools files, so Dwight has come up with a quick and easy frontend solution to keep the admin section loading 1.11 and allow the template to load 1.2 instead!

Thanks Dwight!
