If you have a Wyse WY-470 video adapter and either a Wyse WY-890N or WY-660 monitor, you may experience a screen synchronization problem. This problem occurs when running a graphical MS-DOS - based application full screen and then switching to a window.


The vertical refresh rate is not being set properly.


To avoid this problem, choose either full screen or windowed mode before you allow your application to start displaying graphics.
