Bug

Along with Blogger's periodic refusal to publish for hours on end (hence the minimalist white-on-white layout around noon today), and Rogers's appalling unreliability as an ISP, I am also currently plagued by a bug that sometimes causes the Safari browser on my iMac G5 to hang when I load the page. But only Safari, and only on the G5, and only sometimes. I think it must have something to do with Google Ads, since it began (I believe) around the time I started running them. But what kind of obscure bug afflicts one browser on one machine, and then only some of the time? Is anyone else having this problem, either loading my page or their own?
