The is a sort of follow on from the colour conflicts with rc_image topic.
I now have a problem whereby I do are fair amount of processing on an image, but
if I have several xgraphic windows up - using rc_array - and the heap store gets used
up during processing and a garbage collection is done to free some memeory up.
The trouble is this clears all my xgraphic windows. I have altered the value of
popmemlim several times, but no matter how large I set it to, this problem reoccurs.
Is there some way of preventing this as currently I have to redisplay the
images after processing.
Thanks
Simon
