Doubledisk Version 2.5
----------------------
Windows 3.1 may try to access "phantom" disk drives if you use
Doubledisk with Windows 3.1. Phantom drives occur when you
use Doubledisk to create a compressed drive. For example, if you
have drives A, B, and C on your computer and you use Doubledisk
to create drive F, Windows 3.1 (and MS-DOS) recognize drives D
and E as valid drives, even though they do not actually exist. You
can use the DRVOFF utility to prevent Windows from recognizing
phantom drives. Contact Vertisoft to order a copy of the DRVOFF
utility.
