tp sell section not working?
I have this problem often and either have to logout to character select or out of the game completely then log back in. This has happened to me in all sections of the TP including the gem store. I really wanted to buy those gems too.

When this happens to me, I usually just close the awesomium process via Task Manager, and then restart the Trading Post. That usually clears it up, in my case.
