Middle Mouse Button Installation Instructions.
------------------------------------------------------------------------------

To automatically install Middle Mouse Button, extract the files from the 
archive file MBUTTON.ZIP to a temporary subdirectory (folder) or to a 
diskette. Then execute the program INSTALL.EXE which will automatically 
install the program files to the appropriate directory for the operating 
system being used. NOTE: If you are upgrading from a previous version, 
you should terminate the currently executing copy of Middle Mouse Button 
before running the installation program.

Once the Mbutton files are copied to your disk all you have to do is execute
"MBUTTON.EXE".  The installation program will optionally create an entry for 
"MBUTTON.EXE" in your "Startup" group (or create a Windows 95 "Startup" menu 
entry). It will then run every time you logon to the system.

To manually install Middle Mouse Button, extract the files from the 
archive file MBUTTON.ZIP to a temporary subdirectory (folder) or to a 
diskette. Then copy the files into the subdirectory (folder) of your choice. 
If installing on a Windows NT system we suggest using the "Win32app\MouseButton" 
subdirectory (folder). If installing on a Windows 95 system we suggest using 
the "Program Files\MouseButton" folder. 

On a Windows 95 installation, the files "MBUT-DEL.BAT" & "YESNO.COM" should be 
placed in the "Windows\System" folder.

On a Windows NT installation, the files "MBUT-DEL.CMD" & "YESNO.COM" should be 
placed in the "Windows\System32" folder.

UnInstalling Middle Mouse Button
------------------------------------------------------------------------------

The installation program will create an uninstall icon for you unless you chose 
to not allow the creation of a program group. To manually remove this 
application from a system follow the instructions below:

Windows NT: Execute the batch file MBUT-DEL.CMD with a command line option of 
C:\win32app\MouseButton (assuming that this is where you chose to install 
the application). After this file executes, you will need to manually remove 
any program groups and icons related to the application.

Windows 95: Execute the batch file MBUT-DEL.BAT with a command line option of 
"C:\Program Files\MouseButton" (assuming that this is where you chose to 
install the application). After this file executes, you will need to manually 
remove any program groups and icons related to the application.

MBHOOK.DLL	A dynamic link library required by the system.

What to do if Mbutton reports that a 3 button mouse is not installed.
------------------------------------------------------------------------------

If you are using a 2-button mouse, you may launch Mbutton.exe with a command line
parameter of /2B. This will allow the Left-Right chord combination to simulate a 
double click or to be assigned another function from the setup menu. You may also
check the "2 Button" option in the setup dialog box; this will save the /2B 
option in the system registry and make it the default mode.

If you are using a 3-button mouse and you believe that the driver supports 3 
buttons, but is not reporting the proper status; you may launch Mbutton.exe with 
a command line parameter of /3B. If your driver does support 3 buttons, this 
should allow Middle Mouse Button to function properly. You may also check the 
"3 Button" option in the setup dialog box. This will save the /3B option in the 
system registry and make it the default mode. NOTE: this option will NOT make a 
driver which only supports 2 buttons magically support 3 buttons. This will only
allow a 3 button driver which does properly report the 3 button status to the 
operating system to function properly for Middle Mouse Button.

Windows 95  mouse drivers will only support a 3-button mouse if the specific 
driver was designed to do so. Many "generic" 3 button mice are dual mode 
Microsoft/Mouse Systems or Microsoft/Logitech compatible devices. The Logitech 
driver will support Logitech (or compatible) 3-button mice, the Mouse Systems 
driver supports Mouse Systems (or compatible) 3-button mice, etc.  The only 
solution for using the middle mouse button under Windows 95 is to use the proper
driver for your mouse. Microsoft supplies a Logitech driver with Windows 95. A 
Mouse Systems driver is available with the CD-ROM version of Windows 95 and is 
also available on the Windows 95 Support area on MSN, the WINNEWS forum on 
Compuserve, and other Microsoft on-line support forums.

A special consideration for some OEM "Mouse Systems compatible" mice is that you
may need to change the setting off a jumper or switch to enable "Mouse Systems 
compatibility". This switch is usually accessible through a small window on the 
underside of the mouse. A few OEM 3 button mice require you to hold down a button
usually the left button) during system power up to enable "Mouse Systems 
compatibility".

DCS is currently developing a "generic" 3-button driver for Windows 95. Check our
Web Home Page and our BBS for availability, it will be available at those 
locations before it is available on the commercial on-line services.

All of the built-in Windows NT mouse drivers will support 3-button mice. (The 
only exception we have found is the "Inport" driver. Digital Control Systems has
a replacement Inport mouse driver. However, sometimes the Windows NT setup
program does not detect a 3-button mouse as having 3 buttons. When this happens 
the first thing to do is to use setup to remove the current mouse driver, and 
then re-install the driver. If this attempt is not successful, you may try the 
"/3B" command line parameter. Or you may manually change an entry in the system 
registry using the registry editor (REGEDT32.EXE).

Using this tool may require system administrator privileges. If you are using a 
company owned computer you may need to contact your network administrator or 
tech-support coordinator in order to obtain the required security access 
privilege. (or to have a technician do it for you.)

See the file MBUTTON.WRI for more information detailing how to edit values in the
Windows NT registry.
