Reported to occur on Windows 10 in examples: wxpython.py, qt.py and hello_world.py. This issue occurs when using ApplicationSettings.cache_path option. Cookies are not flushed when closing app immediately. Cookies are flushd to disk every 30 sec or so.

A similar issue was fixed in the v31 branch via Issue #158.

Issue occurs on Windows.
In v57 it worked fine on Linux, but in v66 the issue occurs also on Linux.

I can reproduce the issue on Windows 7 with the http://www.html-kit.com/tools/cookietester/ url. I've modified hello_world.py example and set cache_path option. If I set a cookie and close app within 30 seconds then the cookie is not persisted. If I wait 30 secs then I can see the cookie appear after relaunch.

Also reproducible with the wxpython.py example.
Also reproducible on Linux with the hello_world.py example.
Issue not reproducible in cefclient sample app.

Fixed in rev c78619a.

If implementing custom cookie managers you have to call FlushStore explicitilly when closing associated browser.
