I had to make some DNS changes the other night, and I'm not sure if OW just isn't taking those very well or what.
In SP10, I was at this page:
http://www.macupdate.com/info.php/id/21518 and clicked the Download Now link. The file began to download, and then stuck. So I kept surfing waiting for it to download. I came back to the manager and it was half blank (see screenshot.)
The file downloaded fine with WebKit.
