Alpha client not adjusting with resoloution

Hi, i just downloaded the alpha client and when i click on it the right side which is the login part of it just poof disappears. my monitor is 1024x768 so I'm thinking that the new client can't adjust automatically with the size of the monitor. even when i don't click anything and try to login at the edge of the screen , again if i click anywhere in the game it disappears again. I really wanna try it so it would be nice to look at this bug. Ty
