A couple months ago, following an "upgrade", suddenly the site layout was STRETCHED OUT all over my screen. tons of wasted space, etc. The really annoying part of this was, I couldn't read any message posts without CONSTANTLY scrolling horizontally, right, left, right, left... (up and down is okay, but right and left is a pain in the ass).
I mentioned this, and it looked like no one else was having any problems. I got past it by shrinking the font size until I could see everything, except, the font size was teeny-tiny.
I use Firefox. Last night I found an add-on called "NO SQUINT". This allows you to adjust the font size INDEPENDENT of the rest of the page. Suddenly, this site "works" for me again.
I thought I'd pass this on. It might help!!!
