well first off it looks like a nice setup you've got there
well problem one - can you not just drag the window bigger to fit one monitor, rather than using there actual full screen button?
problem 2! well thts a weird one! not sure
tell me, what mode of dual monitors are you using? ive got an nvidia card and if i right click on my desktop and click nvidia display, either of the monitors, and then go to the tab on the left nView Display settings. there is a list of modes. which one are you working in?
