Yes, of course there is no better way to do this. I did not say  
otherwise. I just documented what is in there right now. I'll not do  
that again  - I seem to understand you want me to stop contributing.  
I just do not get why right now.

That's obviously the way to go. I also never said otherwise.

Sure. I know. I assumed you know that I know.

Sorry, You lost me here completely. What does that mean? Text widget  
and Tk is not about Cells. I do know perfectly well that I am a  
bloody beginner in re Cells. As for the text widget I'd say I did  
gain some experience (that I am ready to share).

Please enlighten me on how I did something I shouldn't have done. The  
only intention was to say "well, there is something you can use and  
if you do, don't be surprised it behaves like this." Because that's  
the thing I was trapped by. Assuming others might experience this  
also I "bursted out" into a few lines of a short notice - speaking  
from beginner to beginner.

Well, I may be wrong here as I might well misunderstand all of the  
underlying message of this reply, or, even, there is none - if so, I  
beg pardon for implying something which isn't there.
