[dorkie dork from dorktown]

How do you check at runtime if a control is positioned by styles like
Top and Left vs X and Y?

these always return "0"
                                        targetTop = target.getStyle("top");
                                        targetBottom = 
target.getStyle("bottom");
                                        targetLeft = target.getStyle("left");
                                        targetRight = target.getStyle("right");
                                        targetVertical = 
target.getStyle("verticalCenter");
                                        targetHorizontal = 
target.getStyle("horizontalCenter");
