I've also found something very interesting to control the app when it's not in focus anymore with pyHook:
The pyHook library wraps the low-level mouse and keyboard hooks in the Windows Hooking API for use in Python applications. This short tutorial demonstrates how to set keyboard and mouse hooks, what information is available about events, and how to pass or block events.

Python rocks :)

Hi there
ui updates with tkinter will only happen IMHO after your method returns.
use the widget.after() method (check
http://infohost.nmt.edu/tcc/help/pubs/tkinter/universal.html) . Something
like this:
def screenshot(event):
fen1.iconify()
fen1.after(200,doscreen)
i=0
def doscreen():
global i
print " screen !"
i= i+1
name = "session1picture"
name= name + str(i)
print name
myscreen= ImageGrab.grab()
myscreen.show()
myscreen.save("C:/"+name+ '.jpeg')
fen1.deiconify()
If you want ro remove the taskbar entry you can apply the win32 style
MYWS_EX_NOACTIVATE (at least with win2000 or later). This requires C
programming, and is just the first thing that came into my mind.
