Is the workbook shared?

Using Office 2007 Pro w/XP. While making a lot of changes to a copy of an
existing workbook I noticed I couldn't not insert a Text Box. Upon further
review it appears the Insert ribbon has most of the buttons disabled. I was
protecting sheets/adding edit ranges etc. when this may have occurred. I've
uprotected everything, deleted the edit ranges but can't get back to previous
good state. Any ideas where I could check?

Thanks for you help.
