Word Opens Off the Left hand side of my screen

Hi
I have office 2003 pro installed on my comp im running win XP, all the other office programs work fine but word opens off the side of the screen like it was setup for a multi screen option, I need word to work so I tried reinstallation but that did not help, now depredate I done the office updates including sp2, that also did not help.

Dose anyone have any clue as to how to fix this problem???

Thanks in advance for your help
