SYMPTOMS
When you are using a Cirrus Logic SVGA 5402 video adapter and you drag a window to a new location on the screen with the mouse, the screen may not be redrawn correctly.

CAUSE
The Windows 95 Cirrus Logic video drivers are not fully compatible with the older Cirrus Logic SVGA 5402 adapter.

RESOLUTION
To resolve this problem, use any one of the following methods:


 * Set the Hardware Acceleration slider to None. To do so, use the right mouse button to click My Computer, click Properties on the menu that appears, click the Performance tab, click Graphics, move the Hardware Acceleration slider all the way to the left, and then click OK.
 * Change the video adapter type to Standard Display Adapter (VGA) or Super VGA.
 * Upgrade to a newer video adapter.

STATUS
This situation is most likely caused by design changes in Windows 95. Microsoft has confirmed that it is not caused by a problem in Windows 95. For further information, please contact the video adapter manufacturer.
