Newbie Questions on Forum Display?

It was only Zelaron that had this (zoomed out view), which led me not to think it was a browser or O/S related setting, but rather a site related one.

Thank you Randuin for your elquently put statement. I had forgotten to post that I had already gone through the User Profile and User Options, none of which shed any light on my issue. The "Viewing Options" in "User Options" only had two options, one of which was how many posts per thread it would view, and what day's posts I would be defaulted to view. The first option was simply how many posts per page were available, now the font/size of them when being viewed. So thank you for your piercing comment, but perhaps you have another idea?

I'll putter around IE and my operating system to see what's up, but your commentary/ideas are greatly appriciated from the entire community.
