What's going on with the Instant message box? Not sure if it's just happening to me but when I go to IM to send a message to someone I now get a message box that's about a mile long horizontally.
I wish I could tell you that I know the exact reason why this is happening to you and how to fix it, but I can't.
Now, it's not like I haven't seen something similar to this happen, BUT it has always been under special circumstances - say, if someone has included a really long URL in an IM/post, or perhaps if they've included a really wide image. But clearly neither is the case with you because you're obviously indicating that it's happening to you every time you open the Post reply window to send an IM.
This just happened suddenly when you upgraded the forums.
I checked the forum's access_log and noticed that you're using IE 5.0, but I don't really see why that should make a bit of difference - particularly considering that we're using the exact same Advanced Instant Message script now as we were before the recent system upgrade. (That script was one of the very few that has had no changes whatsoever made to it.) Also, more than a dozen other people have sent IMs using IE 5.0 today, and none (so far, anyway) have reported having the same problem.
I'm really sorry, but you're situation has me stumped. I do honestly wish I could be more help, but...
