This article was previously published under Q127767



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.
