I get the spinning beachball before the page finishes loading and the following messages appear in my Console log: (event handler):Undefined value (event handler):Undefined value [1694] http://www.wdsu.com/video/index.html line 40: ReferenceError: Can't find variable: videoplug [1694] http://www.wdsu.com/video/index.html line 44: TypeError: Undefined value [1694] http://www.wdsu.com/video/index.html line 50: ReferenceError: Can't find variable: NewState 37493 1 rdas7 2006-03-24 07:16:56 -0800 Same here. Looks like same behavior as when rapidly clicking several links in an rss feed to open in new tabs.

Not sure why it was there, NSURLConnection seems to handle this nicely. BTW, looks scarily similar to the completely unrelated bug 9802 :) As noted in comment 4, scrollbars in subframes don't work, but this is certainly a separate issue. 49318 10 9370 timo 2006-07-11 10:55:11 -0700 Comment on attachment 9370 fix assertion failure Looks good! r=me 49323 11 ap 2006-07-11 11:23:32 -0700 Committed revision 15337.
