MORE INFORMATION

This situation occurs when an ActiveX Document DLL project runs at the Visual

project runs either at design time or at runtime in Internet Explorer.

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

1. Create a new ActiveX Document EXE project with Visual Basic.

2. Create a Command Button on the User Document.

3. Write the following code to User Document:

  Private Sub Command1_Click()
        Dim frm1 As New Form1
        frm1.Show vbModal, Me
        Unload frm1
        Set frm1 = Nothing
  End Sub

4. Add a new form called form1 in the project.

5. Create a Command Button on this form.

6. Put the following code to the form:

  Private Sub Command1_Click()
       Dim frm1 As New Form1
       frm1.Show vbModal, Me
       Unload frm1
       Set frm1 = Nothing
  End Sub

7. Run the project.

8. Click the Command1 button. Form1 appears.

9. Click the button on Form1. Another instance of the Form appears.

10. Close all the forms.

11. Close the Internet Explorer window.

The following error message appears:

  This browser window (or ActiveX control in this page) is busy.
  Closing this window may cause some problems.

  Do you want to close it anyway?
