Re: Application launch detection

->  SubstructureNotify would produce. 

that's possible - but this is a specific external app launch monitor
progarm issue - personally i'd put it right into the wm and have the wm
handle it since it's going to either map or iconify the window and know
about it already - and luckily for you the bi-product is the wm adding
it to the client list :)
