app crashes on win.close() in older android API

Hi - I'm writing an app which works nicely on my Galaxy S3. It works nicely in the emulator (all API 18+ I believe)

But when I test in an old API10 (2.3.7) it crashes when the win.close() function is called. This also happens if you use the "Back" button on the actual device. Basically each time a window or model view is closed it crashes.

Is there any known issues with older APIs using the win.close() method? I can paste some code, but it's really just a simply window create with a close which is causing the problem.

Thank you for any help.

CLI version 3.2.0, Titanium SDK version 3.2.0.GA Targeting build on Galaxy S2 2.3.7 (API10) emulator (Genymotion)
