Ever since upgrading from SP4 to SP5, I've been having problems with Digg.com. I click on a link to a Digg article in my newsreader, but when the page has almost finished rendering, OmniWeb beachballs and tries to consume 100% of the CPU for about two minutes. Then suddenly everything is normal. I click on a different article, and the same thing happens all over again. Rebooting didn't fix it. Has anybody else seen this? (PowerBook G4, 1.2GB RAM)
