New to server help with vent / full screen

[Predator3088]

Hey me and a friend just started today... We were hoping to use vent to talk to each other however i have to alt tab each time i want to talk to him. how can i fix that?

also when i try to put the game in full screen it does change to full screen but it move down to the lower left corner of my laptop screen(half the game on screen and half off) and i am unable to move it. is there anyway to fix that?

thanks
