Hi Manu,
Its seems odd that you are getting some key events but not all, odd
enough that I can't think of a failure mechanism that might explain
it. I'm afraid you'll need to stick some debugging code into
GraphicsWindowWin32.cpp to see what is happening with the events.
In your code shouldn't need to the setCameraWithFocus, as when you
moving the mouse into the window the CameraWithFocus will be
automatically set - the focus will follow the mouse, except when you
click in one Camera's Viewport then drag the mouse over another
Camera's Viewport, in which case the focus will stay with the original
Camera till you let go of the mouse. This feature is really important
for the CompositeViewer, but for a single window app is pretty
irrelevant.
W.r.t threading it should be OK to create the Viewer in one thread and
then call realize and run the frame loop from another, you should just
need to make sure that they are syncronized so that second thread
doesn't start before the first one has finished.

In fact I guess this is still linking to the amulti threading issue : I'm
building by viewer in a Thread n°1 (-> one call to createGraphicsContext()),
then I call run() in a second thread (--> call realize())...
what is the good solution in this situation ? should I prepare everything in
thread 1, call realize() here and only then call run() or frame() in thread
2 ? or should I do everything in thread 2 only ?
I'm still not understanding what's happening :-)...

events (at least !) any more... :-( (but is still receiving normal ascii
keys like 'a' or 'q' for example)... any idea what I'm missing ?
