Steps to Reproduce Problem

1. Start the 16-bit version of Visual Basic 4.0, or if it is already running, click New Project on the File menu.
2. Use the following steps to create an OLE server called MyPop:
   
   
   1. On the menu, click Tools.
   2. On the Tools menu, click Options, and then click the Project tab.
   3. In the Project Name text box, type "MyPop." In the StartMode group, click OLE server. In the Application Description text box, enter Pop OLE server.
   4. Click OK to close the Options dialog box.
3. Use the following steps to create a class module:
   1. On the menu, click Insert. On the Insert submenu, click Class Module. The code window for the Class1 class module appears.
   2. In the Properties window of the Class1 class module, set the Instancing Property to 2-Creatable MultiUse, and set the Public property to True.
4. Add the following code to the Class1 code window:

          Private Sub Class_Initialize()
             Beep
          End Sub
   
          Private Sub Class_Terminate()
             Stop
          End Sub
   						

5. Add a label to Form1. Set the Caption of this label to "My OLE Server."
6. Press the F5 key to start the program. Minimize this instance of Visual Basic.
7. Start a second instance of Visual Basic 16-bit. In the Project window, Form1 is highlighted.
8. On the File menu, click Remove File to remove Form1.
9. On the Insert menu, click Module to create a module. The code window for Module1 is displayed. Add the following code to the Module1 code window:

          Sub Main()
             goo
          End Sub
   						

10. Create another module and add the following code into the Module2 code window:

           Sub goo()
              Set r = New Class1
              Set r = Nothing
           End Sub
    						

11. On the Tools menu, click References. The References dialog box is displayed with a list of all the objects that are available from other applications. In the Available References list box, scroll down the list until the Pop OLE Server check box is displayed. Click this check box. Click OK to close the References dialog box.
12. Press the F8 key to single step through the program until you get to the Stop statement.
13. Press ALT+TAB to return to the client. The client program stops responding.
