Guild Wars 2 64 Bit
I’ve been using the 64bit version almost since it was available. Haven’t had that problem. On the other hand what you have described has happened before while using the 32bit client (others have had the same problem before). Never figured out the exact cause but the mostly likely cause is some other app stealing focus. Tracking it down would be tricky but there is a program(that I don’t remember the name of) which tracks window focus events.
Edit: wasn’t too difficult to find the focus tracker http://www.adminscope.com/downloads/window-focus-logger-gui/

I had a similar issue years ago caused by nVidia’s ?Gameworks? (not the driver… the add-on app that “enhances” your gaming experience… similar to AMD’s Raptr). I couldn’t solve it without uninstalling the app. Some anti-virus apps did the same thing too, but I’ve noticed a “game mode” setting with mine, which presumably is to avoid focus stealing.
