I just downloaded the Sage, and it really seems very good.
I thought I remembered a post this week or last, with a link to another dictionary program, but I couldn't turn up anything with a search of the forums. Is Sage what you're using now, Mouser? I know you share my love of such programs, so I'm interested to know what you use.
My Visual Thesaurus is brilliant, but sometimes I need more of a definition, and I would especially like to have etymology, since I often use this. There is a very pretty Konfabulator (the transition to calling it 'Yahoo Widget Engine' will not be easy for me!) dictionary widget, which can search a number of online dictionaries - that will probably be my choice when I'm connected, but I need something for online use too.
