|You mean Toshiba qosmio- which one.|
How about you try to check the status of it in device manager.
you can search device manager in the start menu, the result should come under control panel.
Click on device manager and go to Mice and other pointing devices and double click it and double click your trackpad.
You can try to right click on the trackpad symbol on the windows taskbar and change settings there.
Don't know if that helped.
