ctrl-mouse drag does not work

[Andreas Höschler via Discussion list for the GNUstep programming environment]

Hi all,

I usually start a drag operation with ctrl-drag in my apps. I just realised 
that this (no longer) works under GNUstep. Instead a context menu is raised!? I 
first thought this was due to a WindowMaker setting. But I see the same 
behaviour under xfce. Has this changed in GNUstep over the years? On MacSOX and 
with the old GNUstep tree (we were using years ago) we could happily use 
Ctrl-left-mouse-down and then drag to initiate a drag operation. Can this be 
reenabled somehow (may be with a global default) in the current GNUstep release?

Thanks a lot,

 Andreas
