SYMPTOMS

When you use a Microsoft Office 97 program under Microsoft Windows 95 and you use a Cirrus Logic GD546x video driver, the computer stops responding (hangs).

CAUSE

This problem occurs when you use the Cirrus Logic CL-GD546x video driver, version 1.31 (4.03.00.1131) for Windows 95.

WORKAROUND

To work around this problem, use either of the following methods.

Method 1: Reduce the Acceleration Setting

To work around the problem, reduce the hardware graphics acceleration setting for the video driver. To do this, use the following steps:

On the Start menu, point to Settings, and then click Control Panel.

In the Control Panel dialog, double-click System.

Click the Performance tab in the System Properties window and click Graphics.

Move the Hardware acceleration slider one tick mark to the left of the Full setting.

Note that the following comment appears in the window:
```
      Most accelerator functions: Use this setting to correct
      problems with the mouse pointer. 
```

Method 2: Change the Video Driver

To resolve this problem, change the video driver to one that is provided by the video card manufacturer instead of using the generic Cirrus Logic driver.

Alternatively, use the generic Cirrus Logic driver and an updated driver when it becomes available. To do this, obtain it from the following sources:
