BUG: Screen Saver Does Not Start PSS ID Number: Q111334 Article last modified on 05-10-1994

WINDOWS

= 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.
