---------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows Software Development Kit (SDK) for Windows
   version 3.1
---------------------------------------------------------------------

SYMPTOMS
========

A screen saver does not start on a window that continually changes its
text. SetWindowText() is called, or a WM_SETTEXT message is sent to a
window to change its text.

CAUSE
=====

When calling SetWindowText() or sending (or posting) a WM_SETTEXT message,
a WM_MOUSEMOVE message is also generated to the window, even though the
mouse did not really move. This WM_MOUSEMOVE message prevents the screen
saver from starting.

STATUS
======

Microsoft has confirmed this to be a problem in Windows version 3.1. We are
researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
