xwd debug assistance

[Jens Owen]

Dave,

Is it possible you are "picking" an overlay window?  Try using one of 
the options to xwd that allow you to specify a window ID.  You'll need 
to use xwininfo to determine the ID of the actual window containing the 
image you want.

You might also look for special options on HP's xwd, they may have modes 
to support multiple layers.
