Well, my problem with buzzflash started, maybe, two weeks ago. Around either the 10.4.3 upgrade, or possibly, the Security update after that. Quite recently, in fact. When it doesn't work, it either comes up with a blank page, or more frequently, the URL is something that ends with ?=four digit number, which is, I suppose, an internal database which launches the final (exterior) story. I'll see that forwarding URL and a half-finished progress bar, and of course, the revolving rainbow wheel.
This is a truly severe problem on the websites affected, and Apple should fix it posthaste.
