Random thought.. there *has* to be a better way of finding out when a
usb device is plugged in...

(not that I know how, but I haven't needed to find out either..)

	This helps a lot,  there was actually a confusion in window
names as you
	mentioned . I tried this now for notepad while opening notepad
on
	desktop , it worked :)
	
	Import win32gui
	hWnd = win32ui.FindWindowEx (win32gui.GetDesktopWindow(),
	None,"Notepad",None)
	
	Value of hWnd I get :
	object 'PyCWnd' - assoc is 00B4E620, vi=<None>,
notify=0,ch/u=0/0, mh=0,
	kh=0
	
	Should this be applicable to locate popups on desktop (may be
during an 
	application installation, as we get like - while connecting a
new
	hardware on USB - "New Hardware found" ) , guess there's an API
	AnyPopup() for this,  any imputs on this will be of great help
too .....

	A couple things to check:
	Are you sure the window class name is correct ?
	Is the desktop window actually its parent ?
