I have a user with W2K and Office 2003. She runs macros in Excel in a
spreadsheet that takes data and then creates a new spreadsheet with that data
in it. It is very large. Other users with similar resources can run this
just fine. (She has more memory, speed and space than anyone could ever use..)

1/2 way through the routine Excel locks up. Then it says, "Excel cannot
complete this task with available resources. Choose less data or close other
applications."

Then she gets a Microsoft Visual Basic Window that says 400. Then she gets
two further windows, one winmgmt.exe and the other ldiscn32.exe, both
referring to instructions that reference memory and how the memory could not
be written. One also states the required data was not placed into memory b/c
of an I/O error.

Again, other users with similar resources can run this perfectly, same
office suite. Do you have any ideas?
Thank you!
