SharePoint 2007 javascript error when accessing site actions menu

[FK12]

I am experiencing a javascipt "object expected" error when trying to access any drop down menu like the site actions or trying to create a new list item etc.
This happens only with IE and in FireFox everything is fine!
I am running IE version 6.0.3790.3959.
When I try doing the same in another maching with IE 6.0.29, the menus are fine. Did any one encounter this problem before.
Any suggestions/ ideas will be greatly appreciated.
