With one particular computer, I still cannot see my avatar in the selection screen, equip/trade screen, etc. This is a computer at work, so there is little in the way I can do in terms of drivers and such. But I thought you might want to know.
Hardware
ATI Radeon HD 5450
Software
ATI Driver version 8.821.0.0 from 1/26/2011
Windows 7 64 bit Professional
It likely is an outdated driver issue, and I will look into the possibility of updating.
