// Tool Tip II (01-June-2006)
// by Vic Phillips http://www.vicsjavascripts.org.uk
// A PopUp 'ToolTip' where Delays may be specified for both MouseOver PopUp and MouseOut PopDown.
// On PopUp the 'ToolTip' may follow the mouse with specified offsets until MouseOut.
// Alternatively the 'ToolTip' may be 'Sticky' to PopUp at a specified anchor position.
// This anchor may be the object calling the 'ToolTip' for a static 'ToolTip'.
// MouseOver of the visible 'ToolTip' may optionally retain the 'ToolTip' visible
// until MouseOut of the 'ToolTip'
// The 'ToolTip' will avoid the window edges to always be visible.
//***** Functional Code - NO NEED TO CHANGE
