+      <para>If a Windows 98 VM is configured to use the emulated USB tablet
+      (absolute pointing device), the coordinate translation may be incorrect
+      and the pointer is restricted to the upper left quarter of the guest's
+      screen.
+      </para>
+      <para>The USB HID (Human Interface Device) drivers in Windows 98 are very
+          old and do not handle tablets the same way all more recent operating
+          systems do (Windows 2000 and later, Mac OS X, Solaris). To
+          work around the problem, issue the following command:
+      </para>
+      <para><screen>VBoxManage setextradata "VM name" "VBoxInternal/USB/HidMouse/0/Config/CoordShift" 0</screen></para>
+      <para>To restore the default behavior, remove the key or set its value
+          to 1.
