WINDOWS
Summary:
For performance reasons, the Microsoft Windows graphical environment
does not use the MS-DOS mouse driver even if one is installed. Windows
has its own mouse driver (usually a file named MOUSE.DRV) that handles
mouse input. Therefore, Windows applications can use the mouse as long
as the appropriate Windows mouse driver is installed, regardless of
whether an MS-DOS mouse driver is present.
The Windows mouse driver does not provide any mouse support for MS-DOS
(non-Windows) applications. You must load the MS-DOS mouse driver to
use the mouse with an MS-DOS application running under Windows. You
can load the MS-DOS mouse driver either before running Windows or in
an MS-DOS session under Windows. However, we recommend that you load
the mouse driver before starting Windows because hardware conflicts
may occur if a mouse driver attempts to initialize the hardware after
Windows has started.
The virtual device driver named VMD manages ownership of the mouse
hardware between the Windows mouse driver and the MS-DOS mouse driver.
VMD is not a mouse driver; it simply switches hardware ownership
between the MS-DOS and Windows drivers.
