I downloaded and installed this utility without apparent difficulty. I can
see the "Remove Hidden Data" entry in the File Menu when I open a new, blank
document.

The problem is that I cannot see the "Remove Hidden Data" entry in the File
menu when I open a previously created document that I would like to cleanse.

While the previously created document is open I can see that 'rhd.dot' is
checked in the Tools|Templates and Add-ins|Templates dialog box. Also,
"Trust all installed add-ins and templates" is checked in
Tools|Options|MacroSecurity|MacroSecurity|Trusted Publishers

Why does "Remove Hidden Data" not appear in the File Menu when I open an
older file? When can I do to fix this?
