| 8 | If a Windows 98 VM is configured to use the emulated USB tablet
|
|---|
| 9 | (absolute pointing device), the coordinate translation may be
|
|---|
| 10 | incorrect and the pointer is restricted to the upper left
|
|---|
| 11 | quarter of the guest's screen.

|

| 14 | The USB HID (Human Interface Device) drivers in Windows 98 are
|
|---|
| 15 | very old and do not handle tablets in the same way as modern
|
|---|
| 16 | operating systems do. To work around the problem, use the
|
|---|
| 17 | following command:
|
|---|
| 18 | </p>
|
|---|
| 19 | <pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> "VBoxInternal/USB/HidMouse/0/Config/CoordShift" 0</pre>
|
|---|
| 20 | <p>
|
|---|
| 21 | To restore the default behavior, remove the key or set its value
|
|---|
| 22 | to 1.
