I have it on good authority that this month’s css layout produces an errant horizontal scroll effect in IE5.5 on the Mac. I understand that the kind folks at Zeldman.com had a similar problem and actually bothered to fix it. After a brief review of the myriad of compatibility issues they ran into getting cross-platform consistency, I’ve made the “fuck it: it validates” decision. Not a terribly difficult decision, as I don’t have a Mac to test the bugger with. If anybody cares to brew up a quick fix that leaves the display alone on less buggy clients (such as Mozilla or IE6 for Windows I’ll be happy to implement it.
