IE8 issues: Music Free and Joomla 2.5.9

When using IE8 I get some errors.
For instance the sidebar modules gets width 100% when they slide in under mainbody content.
I can PM a login if someone can take a look? Or is it a known issue?

Error message below:

Hi, on IE9 browser don't show any error messages. IE8 is old browser, from 2009. Please upgrade your browser it's free operation, you'll be more secured than now.

Important info:
1) media/system/js/mootools-core.js - this Joomla core file, not Gavick! So We can not help you.
2) xtypo plugin - there is not any plugin in Gavick Template Packages, so you had to install it, by your own. XTypo is a GPL joomla plugin from TemplatePlazza.
3) Only js/gk.scripts.js - looks like ours, hmm.

Thanks, Yes its old but nevertheless, some of our customers will be using it still. I need to fix as many of the issues as possible. There seems to be a fix for Mootool. Xtypo can be replaced by your Typograhy I think. I just haven´t made it work yet. I´m not sure what gk.scripts.js does to the IE experince. I´ll try to sort the others first. -m
