Please fix the trading post
I haven’t had any issues like freezing while using TP, maybe it’s something at your end. You could try to repair your game client and see if it solves the issue. Instructions about that can be found here: https://help.guildwars2.com/entries/28148006-Repairing-the-Game-Client
Make sure nothing is interfering with the Coherent program, as well.
Good luck.
@Brutal Augus: what did Support say in response to your ticket? They are usually very good at helping people troubleshoot issues with the TP. Nearly all the time, it turns out to be a problem on the client side (sometimes over-ambitious anti-malware, sometimes something about how Windows or the Mac is setup, sometimes something odd).
I was basically told to do what Shadow suggested, however, despite having ran repair through terminal I am still experiencing occasional game freeze via trading post.
