help! can't get whole screen on monitor

[miss potc]

hi there!!

i'm back! my account 'disappeared' after reaching level 9 pirate status and finishing doc grog's jobs, so i had to create another account. now that i have a new account, i can't get the whole screen to appear on my monitor, i'm only getting 3/4 of the screen. is there something i can press on to change it? i can't scroll around the page or page up or down, so i can't see the bottom of the page. i can't even create a pirate.

please help.
