I have a 23Mb Spreadsheet which has links to various other sheets and
PowerPoint Presentations. When I select certain sheets to create a copy, the
following occurs

1. Book 1.xls created

2. reading data.......

3. calculating

but at 15% complete Excel shuts down with no warning or error message. if 3,
4 or 5 sheets are open which are not connected, they also shut down w/o
saving or promptinig for a save.

I can create a copy with some sheets but as soon as I include other sheets
the problem appears. Memory does not seem to be an issue, nor which computer
on the network I use. Network profiles have been reset, no good, even a roll
back to a copy of the sheet that worked, but that now does not work..

Something, somewhere is conflicting or is corrupted,  any ideas
