I had this issue 6 months ago on my locked down IE at work
, that's still a problem but I noticed this week that I have it here at home on Chrome too.
Please see screenie
, I turned on sigs and profile pics for this, but it looks the same without them
It's exactly as I described in the other thread: When i view a thread there's an additional empty grey column down the right hand side. it moves the reply buttons in one third of the inner grey column. The text window is the correct size (compared the the green background) but the text doesn't go in to the last third.
The other annoying thing is the date/time of the post is all mashed together, so when an old thread gets bumped I think it's new :)
