John,
you are so right, the script was exported without the mouseover layer.
You wrote Xtreme in your post and the german version of WD is named MAGIX XTREME WEBDESIGNER. I thought it means the same.

Thank you and all other again for your explanations and tipps. This forum is really good and is helping me a lot. Unfortunately the german support for WD is not so good, so forgive me, if i bother you with dumb questions
