Steps to Reproduce Behavior

1. Create a Standard EXE project with 3 forms (Form1, Form2, and Form3).
2. Place one CommandButton on both Form1 and Form2.
3. Place the following code in the Command1_click event on Form1:

         Form2.show vbModal
   
   						

4. Place the following code in the Command1_click event on Form2:

         Form3.show vbModal
   
   						

5. Add the following code to the Form3_load event:

         Dim a, b
         Debug.print "Loading Form"
   
   						

6. Add the following to the Form3_Unload event:

         Debug.print "Unloading Form"
   
   						

7. Press the F5 key to start execution.
8. Press CTRL+BREAK to enter debug mode.
9. In the Immediate Window (CTRL+G), enter "Command1_click" (without the quotes) to activate the Command1_click event.
10. Press CTRL+BREAK to enter debug mode.
11. Press the F8 key to Begin Stepping through code.
12. Click the Command1 button on Form 2.
13. Press the F8 key to step into load event of Form3.
14. When you reach the Debug.print line (before executing this line), stop program execution.
    
    At this point, Visual Basic will appear to continue running the program. Click the End button again. The Visual Basic IDE will disappear or Visual Basic will generate an Invalid Page Fault(IPF) error message.
