If I click Details, I get:

"EXCEL caused an invalid page fault in module EXCEL.EXE at 015f:3007abc7"

And continues with a set of numbers and letters under the heading "Registers".

It happens when running under Win 98 and also happened under Win XP, in a
brand new PC... I've reinstalled Excel but the problem is still there.
The trouble is that my data is in columns and, in Excel, I need it also
separated in columns for further processing... Copy and paste is of no use,
since I get all the data in the same column...

Any idea of what can be done to solve this?
