Paradise VGA Professional Card User Notes - Version 1.1 - page 3

Microsoft Mouse and IBM PS/2 Mouse Users
****************************************
If you are installing your mouse driver by way of a program such as MOUSE.COM
or have your mouse driver installed through the CONFIG.SYS file, you may have 
problems when using the VGAPROF utility to switch to non-VGA Hercules, CGA or
MDA modes.

When using the Microsoft Mouse driver (version 6.1 or later) or the IBM PS/2
Mouse driver you will need to use a special procedure when switching from VGA
mode to Hercules or CGA modes.  Rather than choosing "Set Hercules Mode" then
"Exit to DOS," you should choose "Set Hercules Mode" then execute the menu
option to "Reboot System in Current Mode."  This option will allow your system
to re-initialize in the currently selected video mode.  At this point you
should re-install your mouse, or if your mouse is installed in CONFIG.SYS, it
will re-install automatically.
