It includes video display drivers, video overlay drivers and external movie drivers. We have identified many of these problems as bugs in the driver code and not in APW. If you are using any of these devices or drivers, and run into any of these problems, you may wish to contact the manufacturer to see about the availability of updated drivers. ---------------------------------------------------------------------- DISPLAY DRIVERS ---------------------------------------------------------------------- ATI VGAWonder XL (Version 3.1) - Screen refresh problem while opening files on net in 32K mode.

Instead of a nice fade out, the entire object flashes repeatedly as it disappears. The driver performs the ROP we request by doing 5 passes over the bitmap. Orchid Fahrenheit 1280 (ORCHIDF.DRV dated 8/10/92) Note: earlier versions of this driver had many more problems, please ensure you have the latest version. - Screen does not redraw properly when graphics and movies are imported in 256 color mode.
