Hi David,
Wow that isn't what I expected either and I was hoping the same thing
as you! I can't check it in 6.4, but in 6.3 it didn't work that way.
Well, it seems that I have to continue writing my own zoom code and
that it wasn't a waste of time writing it. Only some minor issues I
have to face (like re-drawing the ROI's in the same pro****tion as the
zoomed image) ;-)
Thanks
