Is it correct to say that if a canvas is transparent, it will never receive damage events? We are currently running NeWS 1.1. In the code that I have written, it appears that if the canvas is transparent NeWS will not generate damage events for it. Is this true in X11/NeWS? or is it a bug in NeWS 1.1 that X11/NeWS has fixed? I am posing this question because I do not recall reading anything in the NeWS 1.1 reference manual that explicitly states that transparent canvases do not receive damage events.

I too had a lot of trouble with damage events... I don't know about transparency, but I did discover that when using lite, only one canvas got the event. In particular, for a lite window, the frame canvas always got the damage events, not the client canvas. I tore my hair out for days before discovering this. Bryan M. Kramer Xerox Canada Inc.
