Nothing here either (Opera 11, Windows). Seriously guys, Sproutcore is so horribly not-cross-browser that it's a joke. Please stop making sites with it.
SproutCore 1.x, the current stable line, is in use for a number of major sites that work across a large number of browsers, including IE7 and IE8.
@tomdale's comment above provides some context for the rationale behind using a developer preview for this site: http://news.ycombinator.com/item?id=2598829
I must admit I haven't checked right now, but at least a few months ago the site was all about how awesome Sproutcore is, but accidentally neglected to mention that there are common browsers on which it does not work. I had to install and try to use it to figure that out.
IMHO this is a serious attitude problem; launch first, make work later. That's all right if you're open about what's missing, but the Sproutcore site makes promises ("it works") that it can't keep.
That's what I get now using Opera 11.11 32bit on Linux.
