Arkleus: allow user's to adjust volume all in one click and drag motion.
Arkleus: never allow volume to be less than 0.
DoubleClick: This fixes the known issue with DoubleClick where the
focusManager tries to access the stage when it doesn't have access to
it.  This was part of the Tooltip.swc file.  It also fixes a support
case issue for Case# 00033810: IMA3 Issue [Veria, PID 726562].
