Had the same experience, now fixed. Thanks for posting, OP. I thought it was just me.

Note to self. Always close HTML comments.

Its working properly now. Thanks jeff!

This looks like it is happening with Internet Explorer. I'll try to fix it. In the meantime, try Firefox, Safari, or Chrome.

Hmmm...a different user here. Looks normal to me.

Have you shut down and restarted your browser? Have you rebooted your machine? I would recommend that you do those things first to see whether either will solve the problem.

Is it just me? The forum page is spread far across the screen but when I open individual threads the page is squeezed together with empty white space on either side of the screen.
