I'm working WebHTTrack(httrack-3.32-2) on MacOSX10.3.3.

Even if I quit webhttrack in a terminal, Mozilla does not quit.
The reverse thing will also break out.
In the version of before 3.32-2, they were operating normally.

log: 
/usr/local/bin/webhttrack(2894): nasty signal caught,
cleaning up..
/usr/local/bin/webhttrack: line 59: kill: (2906) - No such
process
/usr/local/bin/webhttrack(2894): ..done
