I am automating an excel spreadsheet by using a userform with several
textboxes and a flexgrid. It works fine, but every so often for
whatever reason, the file size of the excel file increases in a very
large manner. I started with a 43kb file and it was working fine. Then
I noticed my machince was so and when I checked the file size it was
like 33Mb, but if I go back to the original file and redo everything it
is fine again for a while. Does anyone know what causes this? It has
happened in both Windows XP and Windows 2000.
