Need some help with dual displays

[is14fun]

I completely reinstalled windows xp home edition and solved most of the problems I was having with Hoster. Namely the database files and importing songs. Now, I have just one problem remaining. When playing with dual monitors (Labtop and TV Screen), I only get the small picture box in the upper left corner of hoster, I don't get the secobd window on the comuter screen. I used to get this but not now. The picture is fine on the TV screeen and in the small box on the hoster program. I have tried doubling clicking, restarting with tv on, rebooting, Still the same old problem. I have The Nvidia GeForceFXGo5600 with version 6.14.10.5401 drivers. Does anyone know how to resolve this?
Thank you
Bob
