Trading post doesn't work for me ..
Sometimes I have that problem, too. We talked about this in that thread:

But as I found out just a few minutes ago, if you open your bag and do a right-click on a specific item that would be sellable and choose to sell it at the trading company, it will open the Trading Company window and load that item/ all your stuff (really fast), so you are able to sell them.
In that case my gems (and the armor preview) are displayed, too.
Does that work for you?
No, it doesn’t ): .
Yeah, that’s weird. I just discovered that it is fully working for me now (gem display, bag search/ display, armor preview), also when I open it normally.
