I am using an EXcel XP workbook which is relatively small in terms of the
amount of data it holds. Several of the rows keep 'disappearing'. If I try
to 'unhide' them nothing happens. If I hover the mouse pointer of the row
markers it will allow me to drag them wider. I then save the workbook.

After making some more changes in other parts of the workbook the rows have
disappeared again.

I can't work out what is happening as it doesn't seem to be any of the
formatting options. And as far as I can tell I am not changing any settings
by accident.

Hopefully one of you clever people out there will know what the heck I'm
doing wrong.

Thanks in advance of help.
