PopupContainer widget causes exception onUnload

[ornus]

PopupContainer? widget is unregistering all windows on unload. if some window is showing content from different domain it's not accessible and a security exception is thrown in the middle of the process.

I don't understand. How can you show content from a different domain? Are you using an iframe? In any case, please attach a testcase to the bug.

I encountered the problem when I have a text editor (FCKEditor in this case) on the page which uses iframes. I'll try to reproduce the problem, but it wasn't consistent. I fixed it by simply putting call to unregister window method in a try/catch scope and ignoring exceptions.

patch to fix the problem. I failed to create consistent test case, but with this patch occasional problems I had dissapeared

We don't do this anymore in 0.9, so no longer a problem (we only listen to events in the current window)
