An operatic inquiry

Earlier this summer the Internet Explorer on our computer became FUBARed, and we've been using Opera (which is really better in just about every way) since. The only problem I have is when I read some blog templates, including this one and the one used at placed like Fanboy Rampage and The Hurting. Specifically, the right-hand column on this template (the left-hand one on the other examples cited) gets pushed all the way down to the bottom of the screen, still on the right but located beneath the content in the other column. Has anyone out there encountered this problem, or come across/used a solution for it? Barring that, any ideas on where I might find a better, Opera-compliant template?
