Steps to reproduce (it may not always happen).

1. Run Narrator on Windows 7

2. Run HelloComboBox (or similar) FX app

3. Open the combo box in the upper right of the window

4. Use the arrows to navigate to "Option 1", "Option 2", etc.

5. Dismiss the combo box selction

6. Exit the program

On my system, the program relaunches itself indicative of certain crash-on-exit problems.
