Just upgraded to Excel 2007 from Excel 2002.
Created a new XLS from an XLT & now cannot edit a certain text box. Have
tried saving as a XLSX but still cannot edit the text box. Tried selecting
'Design Mode' from the Developer tab but still no change. Tested on two
other client machines & can edit the same text box from those two machines
but not mine. All 3 clients have Windows XP & Office 2007. Please assist.

Thanks.....
