Insert new worksheet option is greyed out. Why?

In Excel 2003, can no longer insert new worksheet into an existing workbook.
There's about 70 sheets at the moment, but we have several books with more
sheets and no problem. Anyone recognise the problem/know how to sort it?

Is the workbook protected?

Yes, as it turns out. Another user had protected the book without notifiying
anyone! This has now been resolved. Thank you - I couldn't work out where to
look!
