Description

On my system I put a window.onerror to monitor errors that could be giving to users.

window.onerror = function(m, u, l){

jQuery.post('sendMail.php', ....)

jQuery.dialog ....

});

Once you have done this many errors were reported, however one very often and without explanation.

Uncaught TypeError: Cannot read property 'style' of undefined

Please ask for help on stackoverflow, the jQuery forums, or in the #jquery irc channel.

Please don't disregard this as "Not a bug". It's a very real error, that seems to be browser-specific (I get it in Chrome and IE, but never get in Firefox) and difficult to reproduce - it happens in the most annoyingly inconsistent way. I failed so far toof figure out why does it happen in the first place, but it *seems* to have something to do with animations. If I manage to get a (unminified?) stack trace, I'll put it here, but that might be difficult in my case.
