I'm just another user, but I think that happened because of someone with a LONG user name... and that is forcing everything over to the right since that long name is not wrapping (I'm not there, so I don't remember if that long name has any spaces or is justrunalltogetherlikethis)
As John points out, the PrPro CS5 forum suffered the same fate. Not that long before, the CS4 and Earlier forum had that problem, but as soon as that post fell to "Page 2," things straightened out. Why some people need to choose a screen name that contains the entire Gettysburg Address, is beyond me, but is their option. Time, and posts, will soon sort this out.
