Yann,
I don't know if this is causing your problem or not...
I may be totally off base here....
I have noticed some odd behavior as well.
Running the microwindows demos on XFree under Linux.
The best way I can describe is to say that the system
seems to be frozen until you move the mouse.
I traced this down to the select call in nanox/srvmain.c
at or about line 403 GdGetNextTimeout is called to see if there is a
timer running. If there is no timer running "to" is set to NULL.
This causes the call to select to block indefinitely.
If you replace the "to = NULL" with something like:
{
to = &tout;
to->tv_sec = 0;
to->tv_usec = 1000;
}
You get a much happier demo.
