I think it can do it, though, atm it's not optimized to handle very
huge number of rows.
I guess it reduces then to know if replacing the listbox with a
stringgrid actually improves something (the less we would want is to
do a back step) by trying with a big case, if it works but still have
problems, I might help by building a new grid (something like dbgrid
but not tied to db) to handle it.
I think we would need a/some voluteers with very big projects to
actually test this (I have not seen a very huge list in messages view
btw)
