Currently I am dubugging a problem with the graphics object.
It seems that the vml shape triggers mouse events..
unfortunatly the mouse fil in IE faile miserably..
the line: (82)
var tt=target.type;
throws an error of "Failed" when you run the mouse over the shape you have
drawn with the vml object.
