I have been trying to get the pixwin function pw_copy to work for some
time now.  I can't seem to get it to work.  Are there any known bugs with
it ?  I have included a sample program which shows what I am trying to do.
I want the pixwin from main_frame copied into the pixwin in main_frame2.
On all the machines I have tried, the main_frame2 pixwin remains blank.
(Sun 3 - OS 3.4,3.5,4.0.  Sun 4 - OS 4.0)

Thanks in advance.
