Hi Barbara, If I click on a feature located at POINT(2552356 5693550) (near Angerhausen, South of Duisburg) I get a GetFeatureInfo-Request with the BBOX 2546405, 5692856, 2547405, 5693856. And of course the popup is placed at the wrong coordinates and the GFI-Request is empty.
IMO you should try to search the error in the BBOX creation-function. Regards, Marc PS: I'd guess that this problem should arise in IE as well... haven't tested though.
