Can't scroll to Row 1 in a WorkSheet

[KerryFSA]

In a workbook with several sheets, I can't scroll up to row 1 in one particular worksheet. Can only go to row 2. Other sheets behave normally. Any suggestions? Split and freeze Panes are not activated. Thanks.

Has row 1 been hidden?

Thanks for your response. No, it wasn't hidden. And I just reopened the worksheet now and all is ok. However, I did that previously with no effect. I also noticed, before I saw that the row had become inaccessible, that the result of a copy and paste macro was off by one row.That wouldn't happen with a hidden row, would it?
Any other ideas what might have happened?

Glad it ok, I can only think it was hidden, or the row height had been set to something very small.
