Hello list,

I brought this up already once, but no one replied, so I'd like to
ping the issue again.
With a 3-4-0 tag build of octave on mingw platform, mouse rotation on
a 3D plot using the fltk backend does not work.
testing as:

graphics_toolkit('fltk');
sombrero(40);

Then clicking on the "R" button.
The strange behaviour is, that the rotation is done in the background,
and the first few events of mouse movement are registered, but then
the display does not change until I force a redraw by minimizing & and
restoring the plotting window.

Is this a manifestation of the already mentioned race condition with fltk?
Or is it a different bug?

I think this is a separate problem.  Similar things happen in the
system which has a fix for the fltk "race condition."  Also, things
like this happen under Linux (fc14).  At least under Linux, the
problem is fairly random.  Sometimes the window refreshes and
sometimes not.  Repeating the same sequence of commands,
after quit and restart, does not produce the same behavior.  Often,
but not always, just switching focus to the plot window causes
refresh.

Kostas said he would push the "race condition, i.e. fdopen failed"
fix later today.   It works well for me so far.
