The code is almost bug free.
But the solution is very simple. It will be enough, if you remove the line app = wx.PySimpleApp().
But the whole script can be done much simpler:

Code: Select all

import ImageGrab, datetime
im = ImageGrab.grab()
date = datetime.datetime.now()
str = date.strftime("%Y%m%d%H%M%S")
im.save(r'D:\Pictures\screenshot%s.png' % str)

Pako
