I noticed when using the Pop Under Window II Script, that i get error messages in IE 7 saying:
ROW 89
Character 1
WIN 2 is Null or No Object.
Code 0

you can see this on http://www.vanessamontagne.com (attention:Playboy style nudity) I have tried that on several, even almost blank html pages and I always get this warning in IE7.

Has anybody an idea how to solve that?

Thanks a lot
