why can i not move the layer, witch settings must be done? in Script/Constant.js ?   what ist a skin here? How ca i  use it?

Hi, following problem: Layers with the attribute  position: relative cannot be moved or changed in size in the normal view, only by changing the html-code. Since definging size or position of relativly positioned layers is no violation against w3c-standards, i do not understand this behaviour. Thanks in advance, David
