After 6-7 years of fairly active Excel use, I have a problem that
baffles me:

When I bring up my most used file, the image I see is offset to the
left---I see no column A. When I hit full screen it makes no
difference. When I try to drag the image to the right by using the
arrow in the bottom right corner, it doesn't work; it will permit
moving it up and to the left (making it smaller) but not all the way
right to fill the screen.

Note: This does not happen with other Excel files I open--just this
one that is my most used.

Thanks for any help.
