Thanks! I'll try it!

The only problem I can see is that I already have a class declared to put in 
a ScrolledCanvas (maybe I should have mentioned that. Sorry.)

To wit:

#!/usr/bin/python
from Tkinter import *
class ScrolledCanvas(Frame):
	def __init__(self, parent=None, color='white'):
		Frame.__init__(self, parent)
		self.pack(expand=YES, fill=BOTH)
		self.photo=PhotoImage
(file="\windows\desktop\screensaver\wacky3.gif")
		
		canv=Canvas(self, bg=color, relief=SUNKEN)
		canv.config(width=1000, height=700)
		canv.config(scrollregion=(0,0, 300, 1000))
		canv.create_image(10,10, image=self.photo, anchor=NW)

		sbar=Scrollbar(self)
		sbar.config(command=canv.yview)
		canv.config(yscrollcommand=sbar.set)
		sbar.pack(side=RIGHT, fill=Y)
		canv.pack(side=LEFT, expand=YES, fill=BOTH)
		Button(text="quit", command=self.quit).pack(fill=X)
if __name__ == '__main__':ScrolledCanvas().mainloop()

Good heavens yes it is rude. Unfortunately I am stuck with Win9x for this 
particular experiment! :-) 

What I am trying to do is pop up a window as a screen saverish app that 
displays information rather than a cute bouncing whatsis. I 'compiled' the 
program with py2exe (a wonderful program!) then switched it's extention 
to .scr. Walla! A badly-behaved screensaver! 

I cackled with Maniac Laughter as as my little script popped up after 60 
seconds! :-)

Now all I have to do is come up with code that will only allow one instance 
of the program to run at a time (I know I saw something to the effect in one 
of my Python books, so no one answer this till I give up! ;-)

Of the five parts of the windows screensaver API, I need:

1. provide a description of itself 
2. distinguish between active mode and configuration mode 
3. disallow multiple copies of itself to run 

I just got "Python Programming for Win32", so I hope the answers lie therin. 
(If I can keep from playing with the cool accounting examples he is starting 
us out with. I never thought that stuff would be this interesting....)

Thanks so much!
