There is a transparent circle at the bottom of my screen with the mouse cursor in it and my touch screen has become mainly unresposive.
Concerning the cursor, I have followed some instructions I found stating that "USB input device" under "Human Interface Devices" in Device Manager should be disabled. This seems to have solved that issue but can I leave it disabled or will something not work?
Concerning my touch screen becoming mainly unresponsive, sometimes I can scroll in my Firefox browser and very very occassionaly I can tap the screen to access something but not normally.
My laptop is a Sony VAIO,
Product Name: SVT1312B4E
ModelSVT131A11M
Any help would be much appreciated.
