Any chance that you can put this 1.7MB file somewhere online (better - zip'ed) so we can test with different browsers? Konqueror (www.konqueror.org) has very good DOM-, CSS2- based "KHTML" engine, and I can't say I have ever seen such (50mb) memory usage with it. ( I tested it on a 1.8MB bug archive file from bugs.kde.org, everything was fine) But of course it can vary depending on file structure. Anyway, I am ready to test with Konqi your file, and tell you what exactly memory usage was. | | __________________________________________________________________ | Razvan Costea-Barlutiu | Department of Radiology, | The University of Chicago | 5841 South Maryland Avenue | Chicago, Illinois 60637 | Phone: (773)834-5106 | E-Mail: cbrazvan@baltan.bsd.uchicago.edu -- Vadim Plessky http://kde2.newmail.ru (English) 33 Window Decorations and 6 Widget Styles for KDE http://kde2.newmail.ru/kde_themes.html Do you have Arial font installed?
