You can do what I do and what a lot of other Widescreen users do utilise that extra space by putting your Windows Task Bar to one side rather than along the bottom - to me this is the norm for widescreen use.
Not only does this free up more space to view vertically but, uses the wasted horizontal space.
try your game with the Task Bar moved. It works great for me and Maxthon browser 'pop out' - maximised view - i only have about 1/2 inch black space either side.
Another solution of course is to revert back to a regular 4:3 monitor.
