Where were the problems? I think the label SVG/VML object is also tied to this geometry!? Right now, I'm creating a textpath instead of the textbox element. I had no problems doing this with SVG, so far. My problem is (as always -.-) doing the same thing for IE. For some reason the textpath in VML is not working... And for some other reason there is in OL a flipping of VML-objects around the y-axis...
