Upgrading to XP while still using Excel 2000

Have recently migrated to windows XP from windows 2000, have noticed that a
spread sheet looks normal but when i go to print preview the document has
shrunk to about 10% of the size. Any ideas?

In Page Setup have you got it set to fit to 1 page?
If so, try Ctrl+End in the worksheet to see where it thinks the end of
the used area of the sheet is. If way off where you expected, either
delete the entire excess rows and columns or define a print area
covering just the data you want to print
