Pete, I Would Go With 2007 If I Were You, Because My Mom Had Some Trouble
Running Excel 2003 Spread Sheets With Custom Macro's Created From Her Work
Place On Her Home Computer While 64 Bit Windows Vista Ultimate Edition Was
Installed On It, Just FYI. They (My Parent's) Have Since Returned 2 64 Bit
Windows XP x64 Edition Service Pack 2, And Have Had No Further Problem's
With Her 2003 Excel Spread Sheets From Work, Just FYI. By The Way, Just In
Case Any Body Is Wondering Why Both My Parent's And I Use The X64 Editions
Of Windows, We Both Have Computer's With 4 Giga Bytes Of Ram, Just FYI. If
You Have A Computer With More Than 2 Giga Bytes Of Ram, X64 Is The Way To
Go If You Have Either An AMD64 Processor Or An EM64T Processor, Just FYI.
