Interesting! I was once a cat with the same curiosity, so...
I wrote a small program that, when started, went into a loop and created the
same number of child windows as the number of cells I could see in Excel on
my 800x600 monitor. I think I cut all possible overhead, but my program was
not able to create all the child windows. So unless I am totally up the
creek without a paddle, I don't think each cell is a window...

On further reflection, I hope that the designers of Excel made no assumptions
as to the max resolution and size of the display device, and therefore cannot
know the max number of cells that Excel might be called upon to display at 
once. Given the absence of virtual memory and the generous 640K limit, I don't
think each cell is a window.

However, how about ONE child window, corresponding to the currently active cell?
(But, but, what about ranges etc...)

This was an illustration of how a senior approaching finals week attempts to 
think.
