I've got a spreasheet (excell 2k win 2k) with 14 tabs, containing 1 or two
pages schedules in each tab along with one pivot table. It really doesn't
contain a lot of data. I keep version control of the results as
filename_v1.0, filename_v2.0, etc. With no change in the layout (I did add a
short macro) v7.0 is about 1 meg in size and v8.0 is 30 megs. (I did add a
short macro)

Does any one have an idea why it would explode in size like that? and how to
fix it?
