Crash when pasting ign into console or dragging the window

Hello, GGG!
I've been enjoying this game so far.But there are two errors that bothers me.
Sometimes, when I paste something(like IGN, item stats)from my internet browser into the console, the game will crash.So I have to log in again.

The other one is When I accidentally drags my game window(I like to play it with window mode on), the game will crash and jump to the login panel.And The crash usually happens when the second time I drag it.
