Quick survey || Jem vs. technology

On my last post, Ivie made it known to me that my sidebar isn't showing up right.

[If you can see a big white space on the left, that's where the sidebar's supposed to be.]

When I looked into it, I found that, for me, Firefox worked fine, while Chrome and IE didn't. I also discovered that the sidebar was not gone, but was off-screen: if I zoomed waaay out, it's still there (and it's pushing the footer down too far). Like so:

I spent such a long time going through forums, which said mostly that the probable cause is A) copying content from Word or somewhere else, which brought incompatible formatting with it, or B) an unclosed <div> somewhere.

Then I spent sUCH. A LONG. TIME. going through all my posts. (I'm just glad I don't have more, which is not something I usually say.) And while I found (and ruthlessly ironed out) some frankly disgusting HTML,

I can't find the problem.

So I need a favour.

Could you please write and tell me:

1. What browser are you using?
2. Can you see the sidebar?
3. If not, do you have any idea when you last saw it?

I would really appreciate it. Your comment doesn't have to be long or flowery. I typically worry that my comments will seem terse if they're too short, but if you write even just write one-word answers, I will be very grateful for the information.

Thank you for aiding me in the fight against the technology. I know with your assistance I can crush its rebellion.

...thank you, Strax. I'll keep your advice in mind.
