Aloha Rosco,
Thanks for the replies from both you and Zubaz. I had also sent a request to Stardock Support and Matt Bertsch, Technical Advisor, recommended a zip file (http://sd.stardock.com/Rosco/fixes/fonts.zip) that contains the following fonts;
ARIAL.TTF
ARIALBD.TTF
ARIALBI.TTF
ARIALI.TTF
ARIALLK.TTF
SEGOEUI.TTF
SEGOEUIB.TTF
SEGOEUII.TTF
SEGOEUIL.TTF
SEGOEUIZ.TTF
SEGUISB.TTF
I had never removed Arial (arial.ttf) so I selectively restored segoeui.ttf first, just so I could be sure which font was used for the labels, and sure enough, I now have my labels back again. Thanks again to all of you for the great support and quick responses.
Mahalo nui loa, Bob
