The subject says it all really... am using Excel 2003 SP2. On each
save, I get a fresh TMP file which, on my now retired workstation
(same setup) were deleted on close:

Xmas lunch.xls
Xmas lunch.xls~RF1783b6.TMP
Xmas lunch.xls~RF21684e.TMP
Xmas lunch.xls~RF22d4bf.TMP
Xmas lunch.xls~RF397407d.TMP

Have Googled but found no answer.

And the anti-virus software we're using (Norman) is set up on this PC
in the same way as my old workstation, so suspect AV behaviour not the
answer.

Thanks for any pointers.
