Try to change the mouse settings to default and check.
Press and hold Windows key + R to open the run window. Type 'mail.cpl' to open Mouse properties window. Go to Pointers tab -> click on Use Default -> Apply -> Ok.
Hope this helps.
Thanks and Regards,
Is any having problems with their cursor changing to a gray button to a zoom tool & zooming in & out while working in Windows 8? If so is there a fix for it?
