*The "offset-pointer"/"ghost window" bug with Spaces has been
resolved correctly (this is my second attempt). This means you can
now use the F8 function to zoom out and drag a window from one Space
to another with your mouse. Unfortunately, due to a known issue in
Spaces itself, you can not drag X11 windows to the edge of the screen
to move them to the next screen.
*A focus problem was fixed -- previously, clicking on an X11 window
that was behind an Aqua window would not always bring the X11 window
to the foreground (but clicking on any other X11 window usually
would.) I'm sure I'll be proven wrong, but at the moment I have fixed
all of the focus problems that I know about.
Thanks a lot for the new release of the Xquartz (not to mention the previous ones!). I have just tested it, and unfortunately (at least in my case) the focus problem persists. Let's hope that 1.2a8 does the trick!
Fortunately, I was wrong (I had forgotten to quit the old Xquartz before my tests)! After testing the new Xquartz 1.2a8, I'm very happy to report that the focus problem indeed appears fixed.
