When Condor 2 is launched, 3 windows are opened (see screen1.png):
- a Condor2 icon
- a Condor2 main windows (let call it the "parent window")
- a "child window" (flight lesson, activation, setup, free flight... depending
on the requested user action). I call it "child window "since it is related to
the parent window. The child window must be closed, for the parent window to
get focus and the user to select a new action.
It's worst noting that the child window it partly above and partly under its
parent window!

My first issue is that the once you click outside the child window , it
disappear under its parent window. As the parent window can't be moved, you are
not able to reselect the child window. The only solution is to kill Condor2.exe
task.

My second and related issue is for flight when trying a lesson. The border of
the "child window" is always visible during flight. Surprisingly, I tried to
make a screen copy, but this border is not present on it (look like the image
is composed of layer, only some being copied!)
