Hi Massimo,

In excel 2003 you get a recalc if the row is hidden/unhidden, but not in
previous versions.
If you double click the row divider (to automatic resize) you get a recalc,
but if you drag the row to to a new height it does not recalc on my system.

It works better if you switch to manual first, then resize, the switch back
to automatic.

This appens both via scripting and operating manually on a sheet.
When I change the row height or the row visibility the sheet is
automatically recalculated.
This happens if row visibility is changed too.
But it never happens resizing columns.
This is not an issue in a small sheet, but in a big one recalculation time
is heavy and it's frustrating waiting for it only for a layout change.
Any suggestion about that or for a way to speed up recalculation?
Thanks to all.
