Why can't I ALT+TAB in and out of OFP?

If you're having trouble ALT+TAB'ing between OFP and other Windows applications, try changing your display resolution setting in the OFP Preferences Program to something lower than your Windows display resolution.

For example, OFP player Jaffo runs Windows with a resolution setting of 1280x1024x32. If he sets OFP's resolution setting to that of Windows, he cannot ALT+TAB between OFP and other Windows applications. Once he lowered OFP's resolution to 1280x960x32, it worked fine.
