I'm not sure if this qualifies as a bug or not (surely its not intentional...so maybe?) but any time I take platinum from my Shared Bank, as soon as I select the amount I want to take out and hit enter, it automatically activates my main chat window for me to type into, which usually leads to me having a mix of w/a/s/d in a long text line, as I use those keys for moving around. I just checked and it does the same thing when I take coin from my regular bank as well when I choose the amount and hit enter. If I click on Accept rather than hit my enter key, it does not do this.
Yep. Happens any time you hit the enter key (instead of clicking Accept) when using the new Quantity window.
