in this._onEvent. One of these references is wrapped in a try/catch with a squelch, the other is not. I think we need to wrap both. Is it necessary to start from 'top' here?

This issue just bit me in 0.4.3 (in that codebase, it is function dojo.widget.PopupManager?.registerAllWindows in src/widget/PopupContainer.js).

My test case: I had a page on a different domain with an iframe that loaded the page that had a dojo menu (the top page did not need to communicate with the iframe page). In that case I got a security exception since the code tries to add a property to top's document.

It seems like reevaluating if it needs to start at top or putting the code in a try catch might be useful. Right now I have an ugly hack to avoid the issue in 0.4.3.

It's certainly better to start from top. The goal is that clicking anywhere in the browser window closes the drop down. But I guess if it's not possible then it's not possible.

I don't really understand Adam's description. There are two references to on the same line, but that line isn't in _onEvent.

Yes, the problem I was referring to would be caused by the _connectHandlers function in diijit/util/popup.js, where it uses, then later tries to do a dojo.connect with its document.

So the first time through _connectHandlers, when no targetWindow is passed, would be the problem case.

I put in a try/catch in lieu of a better solution. Leaving open in case jburke has any suggestions.

OK, I guess this is the best we can do. Closing bug.
