I have a multipage spreadsheet that has certain cells unlocked so users can
enter data. The data that will be entered could be copied and pasted into
the cells, however every time I use the Office Clipboard to copy and paste,
the cell locks after pasting. I can paste using the shortcuts and the cell
does not lock. I want to keep the sheet password protected so the cell needs
to stay unlocked.

Any ideas on what may be causing the problem?
