I have an Excel sheets with dates formatted dd/mm/yy. (eg 18/01/06). I copy
this to a new Excel sheet and the dates change by 4 years and a day - e.g.
the date becomes 19/01/10.

I have tried pasting values, formats but the result is always the same.

I am running Office 2004 on a Mac.

Oh - the spreadsheet I am copying from was created on Windows XP...

My virus protection is up to date.
