Macro security / private certificate anomaly

[Paul_B]

Hi,

Suddenly I am getting Security Warnings when I open some Word
files.

These files were created by me and contain only my macros, which
I digitally certified with Word. In VBE, under This Document,
there are no macros showing.

I set Word's macro security level to "Medium: you can choose
whether to run...". This is one step less than "High: only signed
macros from trusted sources....".

Under Trusted Publishers, I checked both allowance boxes - addins
and templates, and VBP.

Yet I still get these blasted security warnings. There's got to
be something basic I'm missing, or something's broken.

Thanks,
p.
