I've found some reference to problems with Safari 2.0.4 and have fixed one rendering issue related to using fadeTo but I have more severe problems which crash it. The following page will crash Safari when a thumbnail is clicked: http://lonemadsen.pedesign.co.uk/photos.php It uses jQuery version 1.2.6 and the following jQuery script: http://lonemadsen.pedesign.co.uk/script/jquery.photopage2.js Any help would be much appreciated. Thanks.
