Hi

I am automating an excel workbook with Visual C++, with many sheets,
updating cells frequently, and the client (person, not excel client ;0)
)requests this is done 'visually' so the operator can see the worksheet
changing, the cells updating (why, I don't know, it happens that fast).
but....if the user clicks on a cell and selects it, my code bombs out.
It runs fine as long as the user leaves excel well alone.

Is this common? Is this down to my naff code? Any ideas what I can
do?

Cheers

Angel.
