I am using a Satellite Pro S500-139 and am having problems with my F9 key. When i type my palm touches the mouse and send the cursor somewhere else on the page. I have reinstalled the ALPS pointing device and now have access to the advanced setting that i wasn't able to get.
Although i can adjust the sensitivity etc i would really like to be able to use the shortcut to disable the mouse momentarily whilst typing. My keyboard shows that if i press fn and F9 the i should be able to disable the mouse however the function doesnt work. all the other F9 functions appear to work.
