If you work under DOS or DOS + Windows 3.x and that you want to use the mouse
with the installation program, TeXShell and other DOS programs of the distribution,
you must check that a mouse driver for DOS is installed. It is necessary even though
you launch these programs from a DOS window of Windows 3.x, because the DOS
applications cannot use the mouse driver of Windows 3.x. If your mouse driver is old
and don't function in a DOS window of Windows 3.x, get a more recent
driver.
Remark : does he/it seem that, under Windows 2000, the mouse driver
of the DOS windows doesn't work, or don't work with all types of mouse
?
