SYMPTOMS
========

When showing a Modal form containing the Sheridan Tab control from the Load
event of another form, none of the Tabs on this dialog box can be selected.

RESOLUTION
==========

Instead of showing the second form from the Load event of another form, show the
form in the Activate event. The following code could be used as a workaround:

     Private Sub Form_Activate()
       Static AlreadyShown As Boolean
       If Not AlreadyShown Then
         Form2.Show vbModal
       End If
       AlreadyShown = True
     End Sub

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug has been fixed in Visual Basic 5.0 and 6.0.

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

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

1. Start Visual Basic 4.0. Form1 is created by default.

2. In the Load event for Form1, place the following line of code:

        Form2.Show vbModal

3. Add a new form to the project (on the Insert menu, click Form).

4. Place the Sheridan tab (SSTab) onto Form2.

5. Run the project by pressing the F5 key. On Form2, try clicking on any of the
  Tabs on the Sheridan control. None of these Tabs can be selected.
