SYMPTOMS
When a Visual Basic 5.0 application using MSMAPI32.OCX version
5.00.3721 or 5.01.4319 is installed on a Windows 95 system, the application
hangs when it uses the Fetch method of MAPIMessage (if there are any
messages for MAPIMessage to find).
This would presumably occur with later versions of this control as well.
CAUSE
The version of the MAPI .dll's installed are too out of date for this
control to function successfully.
RESOLUTION
Download and install the Windows Messaging System (WMS) from the following
site:
Exupdusa.exe is a self-extracting Windows 95 specific .exe file that
installs WMS on a Windows 95 system.
You may also install either Microsoft Exchange 5.0 or Microsoft Outlook
client and the installation updates the underlying MAPI .dll's.
STATUS
This behavior is by design.
