[Brlcad-users] Mac OS X 10.3.7 Display Errors?

[Paul D. <pde...@ya...>]

Hi,

I'm new to BRL-CAD and working in X11.  

I'm able to create primitive shapes, and once created
they diplay, but the instant I move the mouse, the
shape disappears from the graphic window.  Following
the example in the "Introduction to MGED" typing 

>make sph1.s sph
draws a wireframe sphere.  moving the mouse makes it
disappear.
>draw sph1.s 
redraws the sphere, but moving the mouse again makes
it disappear.  

When I exit MGED, the following lines are displayed in
the xterm window:

Xlib:  extension "XInputExtension" missing on display
":0.0".
Xlib:  extension "XInputExtension" missing on display
":0.0".
Xlib:  extension "XInputExtension" missing on display
":0.0".
Xlib:  extension "XInputExtension" missing on display
":0.0".


I have the most recent version of Apple's X11
installed, but may be missing something else.  Do you
have any suggested corrections to my display problem? 

Also, are there export restrictions for BRL-CAD?


Thanks

Paul
