http://dev.jquery.com/view/trunk/plugins/ui/tests/dialog.html Works in Firefox but in IE 6/7 it generates an error 'expected identifier, string or number' line 98. Note: the dialogs work fine at http://ui.jquery.com/, so its not so much a bug as the implementation on that demo page. Just wanted to point it out. Looks like you have done great work!
