OK, here is an initial stab at a beta. Known issues: - Sometimes the window size is confused when switching video modes. Workaround: switch to another mode, then switch back to the desired mode - After zooming around for a while with PAGEUP, the image freezes and the zoom box is not properly removed even when not zooming. Workaround: maybe changing a parameter slightly will help resync. - If the screen doesn't appear correctly, give it a second to flush any pending updates. You can also try minimizing/restoring the window to force a fulls creen repaint. - Close button most likely doesn't cause the app to exit all the way <http://www.xmission.com/~legalize/fractals/fractdev/FractIntSetup-21.00.beta1.msi> -- "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/>
