I had issues with my keyboard location configurations (layout).
Ingame gw automaticly changed the setup for my keys / became – and so on.
changing that with the shortcut: shift+control fixed that. BUT
after using shft+ctr when i hit the chat box to type gw2 crashed
most time, and i had to restart.
Not beeing sure how this is possible i changed the option in windows
back to only one option for my keyboard setup. Now guildwars isn’t changing
the config and im a happy chatter.
so for all you out there with the same problem, this might work for you aswell
