[OpenLayers-Users] Internet Explorer 8 Issues on adding KML-Layer

[Andreas Schnieders]

Alright, cheers, I did expect something like that!

How would you setup an environment for this? Unfortunately I have only very

objects already and how would them be transferred to the OpenLayers in IE
then?

Regards,
Andreas
