My Toshiba Satellite P850-321 touch-pad isn't working! Help please?

[Luke]

The touchpad on my Toshiba Satellite P850-321 works upon until the point when Google Chrome starts up, then it refuses to move properly. It can still scroll, but only in a very juttery manner, but the mouse pointer will not move unless you are pressing the left-hand mouse clicking button. Can anybody please give me a solution to my problem? Any help is greatly appreciated!

The sensor on the pad is dead mostly where you pointed your fingers most on. so you can change it out, but you need to take out the whole cover.so use a mouse you can get cheap one for 10 bux.
