-------------------------------------------------------------------------------

SUMMARY
=======

When you run version 3.2 of Microsoft Mail Remote for Windows on an IBM Thinkpad
75x Series equipped with the Mwave modem, the system may appear to hang when you
choose Connect Now from the View menu.

RESOLUTION
==========

NOTE: The workaround below is an unsupported switch.

In the MSMAIL.INI file, under the [SFSREMOTE] section, add the line:

  Exclusive=0

The internal default for this setting is 1, giving the Remote client exclusive
control of the Microsoft Windows operating system. Although this switch will now
enable task switching (ALT+TAB), you should not task switch while connected. If
you task switch, you may drop the carrier, or possibly corrupt the mail message
file (.MMF).

Also, there is a modem script available for this modem in the Workgroups
Applications forum.

NOTE: This script is provided by a third party and is not supported by
Microsoft.


STATUS
======

Microsoft has confirmed this to be a problem in version 3.2 of Microsoft Mail
Remote for Windows.

MORE INFORMATION
================

The Mwave software runs at Ring 3 under Windows as confirmed by IBM Mwave
development. The manner in which the Remote client starts a session and
communicates with the modem places the session in Ring 1, thus giving it a
higher privilege than Ring 3. In addition. the Client also runs by default in
exclusive mode. Clicking on "Stop" pauses the session, allowing lower-
privileged rings the opportunity to run their code. Using the exclusive switch
in the MSMAIL.INI file moves the Client out of exclusive mode, and allows the
lower ring to process its code, as if the session were paused.
