konqueror blank screen

Using konqueror on suse 8.2 from the rpm kdebase3-3.1.1-63 I occasionally find a website rendered as a blank screen. For example if I go to www.suse.com I get a blank screen. The browser "thinks" it has rendered the site since I can move around it with a mouse and url links show up and I can click and go to them. I can't find any pattern to this behavior. On other sites I have found certain characters show up as blanks, for example capital letters on one discussion group. I can't replicate this. Changing font has no effect. Anyone have any ideas? Thanks, Henry Harpending
