I have been editing an excel worksheet over many days. I have noticed that
large numbers of comments (but not all) have disappeared. I am not sure
if
they have been hidden or have not been saved. The comments appear to have
disappeared in 'batches', each batch corresponding to an opening, editing
,
saving and closing of the file. The file has been backed up incrementally
and the same comments have 'disappeared' from earlier incremental versions
of
the file.
