[Chameleon] KeyMap question

[Paul Spencer]

Is it possible that this never gets executed and the thread of  
execution goes elsewhere?  Also, is the image being saved in some  
other location entirely?  Chameleon may be changing the imagepath  
from the mapfile setting and you wouldn't know it.

Cheers

Paul
