Stretch command - Does not stretch but moves

Hello and thanks in advance.

 

I just installed Draftsight, and am pretty happy with everything it offers except for a few minor details.

 

Stretch command is the first big problem I have. I use stretch a lot in my daily routine however in DS it just moves the lines not stretch them to the last point.

Am I missing something? Do I need to change something in options?

I watched a few videos in youtube and it seems to work fine in those. What am I missing?
