When I zoom in (a few presses of PgUp key) I get a zoom box display. When I then press the up arrow key, the zoom box moves down. When I press the down arrow key, it moves up.
OK, this is just odd. When I do this (PgUp a few times, then arrow keys), up arrow moves the box up and down arrow moves the box down.
The correct area as displayed then appears in the new image. I find it hard to believe that the keys would work differentunder XP than they would under other Windows 32 bit environments.
No, the keys are all the same under all Windows versions (even Win16).
I suspect that it is simply a matter of reversing the keys as the code works ok.
No, that's not it because *I* am getting the right thing. Are you sure you're using beta 2? :-) Beta 1 had the problem that everything drawn was flipped vertically. Meaning that the keys were processed right, but everything was drawn upside down. With the mandelbrot fractal you don't notice it because of the symmetry, but I noticed it when I got the palette editor to show. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>
