I am running HTTrack from JAVA on linux system. I have specified the user agent
using the -F option as "Mozilla 5.0, Linux, U, Android 4.0.4". But this causes
the java process to exit with exit code 255. If I remove the -F option all
works fine.

I have tried different combinations of the -F but all in vain..
Any help would be highly appreciated.

thanks.
