How do I adjust double tap speed in Windows?
For PenMount Windows Universal Drivers before V2.1.0.263, please change the "Double click speed" of mouse, which can be found in the control panel.
For PenMount Windows Universal Driver after V2.2.0.283, in Windows 2000 & XP (PenMount controller is mouse device), please change the "Double click speed" of mouse in the control panel. In Windows Vista & 7 (PenMount controller is touch digitizer device), please go to the control panel, launch "Pen and Input Devices" in Windows Vista, or "Pen and Touch" in Windows 7, then change the "Double-tap" settings in the "Touch" tab (Do not change the one in the "Pen Options" tab by mistake).
