: Correct me if I'm wrong, but if I have a window (the root window), whose
: window ID is "parent", that is currently displaying and takes up the
: entire display, and I then perform the following operations:
Call your parent window "parent", because the root window
is something else (it's always id 1, and always mapped). I
presume you're not talking about the real root window.
In the code below, you never mapped your parent window in the
first place, and then mapped it again. Nano-X keeps
a map count which could get confused if your map/unmap
calls don't match up.

:
: // Create and open a new window.
: windowID = GrNewWindow(parent, 0, 0, SCREEN_WIDTH, SCREEN_HEIGHT, 0,
: GR_COLOR_WHITE, GR_COLOR_WHITE);
:
: // Map (show) the window.
: GrMapWindow(windowID);
:
: <draw some stuff>
:
: // Remove this window.
: GrUnmapWindow(windowID);
: GrDestroyWindow(windowID);
:
: // Redraw the parent window.
: GrMapWindow(parent);
:
: I should get my original, root window back, should I not? Well I'm not.
: Any idea of what I'm doing wrong? I'm using Nano-X version 0.91.
