Thanks, problem is solved, the panes were frozen.

I think that the pane freezing that Gary mentioned is the likely culprit.
If not, you could try highlighting the entire sheet by clicking in the small
grey area above row 1 and to the left of column A, then Format Row Unhide.

I have a multi sheet Excel file and on one of the sheets, I cannot view the
top two rows. I have tried every way I know and in help to unhide these rows
but to no avail. I am able to access them. One thing I am unable to do is to
try to change their height as I don't get the cursor sign to do this when
approching the select all cells button. maybe this has something to do with
it. The sheet has been protected but is currently unprotected.

Can anybody help please ?
