If I unzip StarDict portable 2.4.8, put Babylon dictionaries into the \dic folder, run StarDict portable 2.4.8, then scan a word, the floating window just repeats the word; example: on the word "Download" I see:
Download; on the word "Portable", I see "Portable"; and so on.
The same happens in the main window.
If I use the same dictionaries oN Stardict 3.0.1...
