Toggling "Enable this device" yields no results
While using a fully updated build of 3.0b on my Cyan, the trackpad will crash after about an hour and a half of use. This issue appears to be sporadic- it doesn't happen every time I use my Cyan. I don't see a pattern to what I'm doing at the time and when the crash happens. One time it was after I had opened a tab in Firefox and another time it was while I was scrolling through OWA in Firefox. A reboot restores the trackpad's functionality.
