Description
no dojo.disconnect corresponds to the dojo.connect in dijit.registerWin
this leads to leaks in at least IE, I think we need to take care of that

Hmm, feel free to work on this.
It's a bit troublesome though... we would need a deregisterWindow() call to complement registerWin(), and perhaps change registerWin() to return a handle... then change all the calling code.
Why there is dojo.connect only for 'onmousedown' event, but 'onactivate', 'focus' and etc. are using doc.attachEvent for IE and doc.addEventListener for other?
When I rewrite registering of 'onmousedown' and used jsleaksdetector it shows that there is no memory leak.
I am not sure that my solution was right. Why there used dojo.connect instead of using direct methods?

FYI, AFAIK I could have used attachEvent()/addEventListener() for onmousedown. I just used dojo.connect() because it's used everywhere in dojo.
The reason I _didn't_ use dojo.connect() for detecting focus is that a dojo.connect() on the <body> node won't work, because focus events don't bubble (except via attachEvent()/addEventListener()).

Apologies, I added the wrong ticket reference to a checkin. It should have been #7873

This was fixed in 1.4, which incidentally switches to using native calls (instead of dojo.connect()) to monitor onmousedown.
