Model : Toshiba R30-A-1CQ / PT343 Windows 8.1
Problem developed that intermittently touchpad would fail to register button presses. - Seemed intermittent. Rebooting machine solved problem for a while.

Updated to Windows 10 via Microsoft Windows Update - problem still occurs.

Further problem examination shows that the button functionality stops working after the laptop is resumed from sleep. - Can now reproduce this 100%. Windows needs to be restarted for touchpad button functionality to be restored.

All Windows updates applied. Touchpad is using Alps driver Ver 10.100.303.105.

Is there a later/earlier touchpad driver which will resolve this problem?
