Unable to bind unload event of the window

[Renato]

When you try to bind the unload event of the window writing

jQuery(window).unload(function(){alert("unload")})

jQuery(window) returns an empty jQuery object, not binding the function to the event.

jQuery itselfs registers for the window unload event to remove all event handlers, due to memory leaks. I guess the other registered unload events are removed, too.

"jQuery(window) returns an empty jQuery object"

This isn't happening on build 1014 IE/Firefox so I assume it's either fixed or needs a more detailed repro example.

Well, there no bug in standard conditions, sorry.

We used the library with a different name, to allow multiple versions of jQuery, replacing "jQuery" with another word but not in case sensitive mode

So the jquery property and the jQuery object were replaced both with the same name, causing the error, as window was managed as a jQuery object.
