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

Start Visual Basic 4.0. Form1 is created by default.
In the Load event for Form1, place the following line of code:
```
      Form2.Show vbModal
						
```
Add a new form to the project (on the Insert menu, click Form).
Place the Sheridan tab (SSTab) onto Form2.
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.
