TITLE   :BUG: Controls Do Not Refresh After Exit From Screen Saver on NT
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:5.0
OPER/SYS:WINDOWS
KEYWORDS:kbVBp kbVBp600bug kbVBp500bug kbScreenSaver

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

 - Microsoft Visual Basic Learning, Professional, and Enterprise Editions
   for Windows, version 5.0
---------------------------------------------------------------------

SYMPTOMS
========

Controls on a form whose ClipControls property is set to False may not
refresh properly after the Screen Saver is activated and then deactivated.
When the mouse is moved to dismiss the Screen Saver, the form reappears but
some controls are not redrawn properly. For example, Textbox controls do
not retain their 3-D appearance. Programmatically refresh the form to cause
the controls to be drawn properly.

This problem only occurs on Windows NT 4.0. The problem does not occur on
Windows 95 or Windows 98.

RESOLUTION
==========

Set the ClipControls property of the form to True (the default value).

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. We are researching this bug and will post
new information here in the Microsoft Knowledge Base as it becomes
available.

MORE INFORMATION
================

Steps to Reproduce Behavior
---------------------------

1. On Windows NT 4.0 Display Properties, enable the "Blank Screen" Screen
   Saver and set Wait to one minute.

2. Start a new Standard EXE project in Visual Basic. Form1 is created
   by default.

3. Set the ClipControls property of Form1 to False.

4. Add a Textbox control to Form1.

5. Run the project and wait one minute for the Screen Saver to activate.

6. Move the mouse to dismiss the screen saver. Notice the textbox has a
   flat (2-D appearance) instead of a 3-D appearance.
