Doc, it's your computer. If anything, on my computer, everything's a little large. I am running my machine at 1024x768 with a 20" monitor.

What you need to do, is if you're running Windows, go to the Start menu, choose Control Panel, then Display. Click on the Display Properties tab (might be Display Settings - one on the far right of the control panel), then choose something like 1024x768. Click OK.

If you're running a Mac, go to the Monitors (or Monitors & Sound) control panel and change it to 1024x768 or 832x624... That'll make it bigger.
