<DIV> </DIV>
<DIV>no, not only green symbols made problems. Other time the red one made problems. Popups opened sometimes near the symbols/marker but were sometimes about a few centimeters away.<BR>IE gave me a white map. And confirm the strange behaviour of map being there after going to another page. Think its a IE problem (IE can´t find a variable, map or something else). But I don´t have any further ideas how to solve this, sorry.</DIV>

didn't help.
