Not sure what to say here, perhaps we should diff the lower level FLTK
routines between your two versions, to see what X11 calls are different.

I've found that sometimes having the server call GsError causes it
to get desynchronized from the client, and things go downhill. One
idea is to comment out the GsError in the GrSetFocus() function
in nanox/srvfunc.c, which is where that's coming from. It's possible
an X11 routine or Nano-X needs to search child or parent windows
for focus if the window requested isn't mapped, we'll have to look into
this. Or it could just be the closed window above, and it's a bug
in FLTK that doesn't cause problems in X11. Remove the error
above and lets see what happens.
