SYMPTOMS

The 5250 or 3270 applet will hang when started. The Windows NT Task Manager's Application tab will not show the applet; however, the Process tab will show it.

CAUSE

The applet is trying to add a font to the system using the following call:

   ::SendMessage(HWND_BROADCAST, WM_FONTCHANGE, 0, 0L);

For the font to be recognized, this call needs to be processed by all windows on the system, visible or not. The applet will continue to wait until a response is received from each window. If an application is too busy to respond, the applet will hang indefinitely.

RESOLUTION

SNA Server 3.0

To resolve this problem, obtain the latest service pack for SNA Server version 3.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

WORKAROUND

To work around this problem, start the 3270 or 5250 applet before the non- responsive application becomes too busy.

Note: This behavior was observed with a large SQL query.
