I was given a Toshiba Tecra for work together with a Logitech Mouse. I am used to using the touchpad so started working with the touchpad and didnt connect the mouse. All worked fine. Later I connected the mouse but now that I want to go back to working with the touchpad I cant. I have taken out the USB mouse plug in, restarted laptop, tried f9 and nothing works - I cant get the touchpad to work - any help please?
