When I upgraded to XP one of the requirments I told the Dell sales rep was the ability to  use old Works files.  "No, Problem, Excell will do it."  Well,  maybe.  But I never was able to and finally had to break down and buy a new version of Works. Still irritates me.

I'm told there is a convertor for spreadsheet files, but it wasn't to be found at the time I was needing it.
