This is down to the details of your setup: which interface (MDI or SDI)
and how Windows is controlling the pointer, and so on. I don't see a
focus shift except when a graphics window is first launched, and that is
deliberate (to bring it to the front). So I can't tell you how to solve
something I never see.

There is a function bringToTop() to do the reverse, to give focus to the
graphics window. You could probably modify it to do what you want:
if you do please contribute the modification.
