SYMPTOMS
========

The Sheridan Panel control does not correctly align to the bottom of a form
after a window is resized if the Visible property of the control is set to False
during the resize of the window.

RESOLUTION
==========

Set the position of the status bar using code. For example, rather than setting
the Visible property of the status bar to True, calculate and set the position
before showing the bar. The following code aligns the bar to the bottom of a
Form before showing it:

     SSPanel1.Align = 0
     SSPanel1.Top = Form1.Top + Form1.Width - SSPanel1.Width
     SSPanel1.Visible = True
     SSPanel1.Align = 2

STATUS
======

Microsoft has confirmed this to be an issue in the Microsoft products listed at
the beginning of this article.

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

Steps to Reproduce Problem
--------------------------

1. Start a new project in Visual Basic. Form1 is created by default.

2. Place a Sheridan Panel on the form, and set its Align property to 2 - Align
  Bottom.

3. Place two Command buttons on Form1. In the Click event for Command1, place
  the following code:

        Private Sub Command1_Click()
        SSPanel1.Visible = False
        End Sub

4. In the Click event for the second Command button, place the following code:

        Private Sub Command2_Click()
        SSPanel1.Visible = True
        End Sub

5. Run the project by pressing the F5 key. Click the Command1 button to cause
  the panel to disappear. Resize the window, and then click the Command2 button
  to cause the panel to reappear.

Note that the panel appears in the middle of the form where the bottom of the
form was prior to the Resize event.

To work around the problem, place the code in the WORKAROUND Section above in the
Click event of the Command2 button.
