Thank you for your help,
I could do it once, but only after I had beforehand split the view (right click inside the window).
I think I could drag another file in the second panel, but I am unable to reproduce it for now.
Should I spilt the view first ? you didn't mention that in your previous post.
Generaly if I try to drag and drop a file within a panel, I can see the small rectangle, but it just put it's name in the current source code, but not the new code itself.
I know henceforth that' is possible and I'll try to figure out.
Regards
jc
