I've submitted this as a bug through the game client, but wondered if anyone else had experienced this issue.
The last two evenings when I completed a Blacksmith Writ on one of my characters and looted the rewards from the container my camera never exited "cursor" mode. When I finished looting the container it didn't switch back to the normal camera mode and from that point on the client switched to, and remained in, "cursor" mode any time I looted a container, opened a screen such as my inventory, the map, character screen, etc. - basically any UI element that normally switches to "cursor" mode and then automatically switches back to the normal camera mode. I could manually exit "cursor" mode with the normal hot key (.) but that would only last until the next time I did any of the above.
This bug persists even if I log out with that character and log on with another character. The only way I can restore the normal behavior of the game client is to completely exit the game and restart it from the launcher.
I had never seen this behavior prior to patch 2.0.2. I have also not seen the UI experience this bug when opening other Writ reward containers or other chests or containers placed around the world. Also, both Blacksmith Writ rewards contained a survey item, though that probably shouldn't make any difference.
