I was trying to load the page http://java.sun.com/javafx/1/docs/api/ off SWAN on IE7.
The page was black in color for a long time and finally it got loaded may be after 7-8 minutes. I could see, there is a JS error in the status bar (detail attached)!
(Note : It was not any browser hang issue as I was able to browse through in the other tabs of the same browser)
