Hi Tony,
I don't think I replied to your comment, which I appreciate receiving, thanks very much. Yes, I tried various options under "Character Set" in the ASCII FITER OPTIONS box, but none of them did anything other than opening up a page with 2 or 3 lines of garbage (or computer language) on it.
I also looked under "Filters" and deleted a line that said
MX excel 2003 XML - OpenOffice.orgCalc(.ods)-import/export.
This did nothing to fix the situation.
Thanks,
Stuart.
