One of my members posted this as a bug on my forum:
You will notice Doc's avatar shows up in this thread and there is no avatar in Doc's thread. It happens when my resolution is set at 1284x1024. If I changes the resolution to 1152x864 it is fine. I'm using IE 8.0.7600.16385 with Windows 7
I wasn't sure if it was still around since we didn't have a report for so long. Note that while he says IE8, he's actually in IE7 compatibility mode. If he takes that off (button in the address bar), it'll go away.
