       NOTE: Machines manufactured by Compaq after April 1, 1994, that
       ship with Windows 3.1 come preinstalled with a virtual keyboard
       driver (VKD) that corrects this problem. Upgrading to Windows for
       Workgroups 3.11 leaves this VKD in place and allows the keyboard to
       work properly. However, if you install Windows for Workgroups 3.11
       to a new directory, the keyboard stops functioning. If you perform
       such an installation, you must manually install the new VKD.

## CAUSE

The keyboard controllers in these machines generate unnecessary interrupts each time a key is pressed and released. The keyboard stops responding because the Windows for Workgroups 3.11 VKD, unlike the Windows 3.1 VKD, does not ignore these extra interrupts.

## RESOLUTION

To correct this problem, use one of the following methods:

- Install the new VKDA.386 file provided with this Application Note.

  -or-

- Install the Microsoft Mouse version 9.x driver. The replacement VKD that comes with this software (MOUSEVKD.386) handles the extra interrupts generated by the keyboards.

  NOTE: You may also be able to download a new VKD from the your computer manufacturer's bulletin board service (BBS). For example, SP0738.ZIP, which is available on the COMPAQ(R) BBS, contains a new VKD that corrects this problem. Contact your computer manufacturer to see if an updated driver is available.

### To install the new VKDA.386 file

1. Insert the enclosed WG0974 disk in the appropriate floppy disk drive.

2. To copy the file to the Windows SYSTEM subdirectory, type the following at the MS-DOS command prompt and then press ENTER

             copy <drive>:\vkda.386 <destination>

   where <drive> is the floppy disk drive containing the WG0974 disk and <destination> is the drive and directory of your Windows SYSTEM subdirectory.

   For example, if the WG0974 disk is in drive A and your Windows directory is called WINDOWS and is on drive C, type the following at the MS-DOS command prompt and then press ENTER:

             copy a:\vkda.386 c:\windows\system

3. Use a text editor to edit the keyboard= entry in the [386Enh] section of the SYSTEM.INI file. Change

             keyboard=*vkd

   to:

             keyboard=c:\windows\system\vkda.386
