Dear All,
Thanks for the info on the buffer strategy creation
bug; I’ll try to add the fix into the code and chapter
today or tomorrow. Did the problem occur in
1.5, which is meant to have fixed it?
The next chapter is about image manipulation, with
a discussion about managed images, and a
few special effects like fading, flipping, etc.
One dilemma I have, is how much to stick with 1.4.2. 
For example, I really need to revisit chapters 1-3
and use the nanosecond counter rather than the
Java 3D timer. In chapter 4, should I mention the
workaround when using ImageIO to create a
managed image?
