[Accessibility] Intermittent crash / relaunch on exit on Windows 7 with Narrator

      32-bit JRE


      Steps to reproduce (it may not always happen).

      1. Run Narrator on Windows 7

      2. Run HelloSanity

      3. Press the "Controls" button

      4. Tab around a while, using the controls (select / deselect the cancel checkbox and radio button, scroll the lists, etc)

      5. Press the "Back" button

      6. Press the "Tabs and Menus" button

      7. Tab or mouse around a few of the combo boxes and select a few choices

      8. Press the "Back" button

      9. Press the "Quit" button.

      On my system, the program crashes and relaunches itself indicative of certain crash-on-exit problems. If I attach a debugger I can catch the crash.

      Here is the stack trace (no FX code in stace).
