- Problems with Third Party Drivers in Authorware Pro for Windows 2.0
- February 1, 1993
- ======================================================================
- This is a list of known problems with third party drivers in APW 2.0.
- 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.
