Hi,
I've recently been trying to use saved images with X-windows.
I am having trouble with the font handling routines, suppose I make a saved
image with
pop11 %nort mkimage something popxlib xlib XFonts
when I try to load a font it executes ok, but the XCharStruct's seem to be
garbaged

the other pointers to structures seem okay, but the nested XCharStruct structures
both seem haywire.
What Can I Do ...................?????
Thanks in advance
