Temporary files named (Spreadsheet_Filename).xls~RF??????.TMP are been left in the Spreadsheet's directory after changes have been made and the Spreadsheet closed. No obvious behaviour pattern, other than it not occuring before a switch to WinXP/OfficeXP (2002), and this series of Spreadsheets including macros and linked data.

Any ideas on this, my usual Forum, before I muse over posting this query on a more Excel-based Forum?
