Rich's approach was the one that clicked in my environment - Windows Vista Ultimate, SP2, 32 bit and Windows Live Mail, Version 2009, Build 14.0.8117.0416. Pretty certain it's not relevant, but just in case - IE 7.0.6002.18005, 256 bit cipher strength.
Don't know if it was an active success ingredient or not, and Sourabh's tip to uncheck the "block download images" option on the Security tab of the Safety Options link on the Options Menu was part of the solution I deployed in my environment.
Also, Anne Hennegar appears to have an approach that might work in other set-ups and environments from mine. She was helpful enough to give me an e-mail response while I was still scratching my head on this one.
Like I said - gratitude to all.
It will be interesting to see what happens on my client's environment - a Windows 7 environment.
