Kurt, I'm glad that you find this dictionary useful. Actually I prefer Babylon because of its ability to identify phrasal verbs and idioms just by clicking over a single word.
Anyway Goldendict is a nice free alternative which allows to manage glossaries made by multiple dictionary programs.
The scan popup feature works really well on pdf, I use it unchecking "only show when selected keys are pressed" which I can't manage to get it to work this way on Firefox/Opera, in that case I double click a word and then press "ctrl+c+c"
Can't this program use the "normal" procedure: Ctrl+mouseClick ?
-Curt
just check "only show when selected keys are pressed" and choose 'control', then press control and mouse over a word.
This works well for pdfs and internet explorer, for other browsers is broken so ctrl+c+c seems the only way for now.
