When use the final 3.31 and try to drop a link on the 
WinHTTrack-Window the program chrash without any comment or 
crash.txt-File. This happens on two systems with XP SP1, i 
don't tested it with other OS.
But i can paste the link into the list and download the URL.
I can remenber that i tested a 3.31 alpha-Version where 
this was working, but i can't remember which version this 
was.
