v. 126.96.36.199 When adding to stack Tooltip displays info for 1 second instead of 1/2 second.
v. 188.8.131.52 Updated Middle Mouse Click handler for better response. Left clicking on the desktop to make it the "active window" before middle clicking is no longer needed. Also the handler does not "eat" the key.
Initial trials indicate the hesitation between middle mouse click and pop up window display disappears using this method.
