I finally managed to find and fix this problem (patch for GTK 
submitted). Should be OK in the current snapshot.

There are a few other fixes and changes for the OS X quartz build:

* The action of sending a gnuplot script to gnuplot itself for display 
using the wxt terminal was not working. (This is what's supposed to 
happen if you have a gnuplot script open in a gretl editor window and 
click the "Run" button.) Gnuplot was opening fleetingly then crashing; 
now fixed.

* On El Capitan (at least) all newly opened gretl top-level windows 
(i.e. not dialog boxes) were being placed at the top-left corner of 
the screen. That seems like a window-manager problem, but I've tried 
to work around it.

* I've added Adwaita to the choice of GTK themes, and made it the 

* Intead of a gzipped DMG file, I'm now distributing the quartz 
snapshot as a signed flat package (pkg file). This is because I've 
figured out how to produce such a thing on Linux - yay!
