Having problems with focusedWindow() method

[carlca]

Hi @cmsj I wonder if I could trouble you to take a look at the problem I have. It's detailed in full on Google Groups where @zzamboni has been very helpful but we still don't seem to have fully sussed out what's going on. Thanks!

Actually, since I posted the above message, I have reached a point where the code is working 9 times out of 10. I'm still getting the occasional error when using hs.application:mainWindow() to get a window reference from an app reference, and instinct tells me it's likely to be some kind of pseudo-random timing issue. I'd be interested in getting your thoughts on it, Chris.
