For those windows users who are having trouble closing the player after it starts, I've made a mod to the version of stealthdave's branch of Chrome Launcher found in the git repository to allow closing the browser on OK/Select or back button press (tested with yatse app for android but should work with everything else).
Steps to Implement Fix:
1. Get the plugin code from stealthdave's branch
git repository (you can download as a zip from the link on the right side if you prefer)
2. Replace your current Chrome Launcher in XBMC\addons\plugin.program.chrome.launcher with the code from the repo
3. Replace default.py in that folder with
my modified file
4. Save the file and all should work
NOTE: you may get chrome's "chrome did not close properly last time" message. It will disappear after a couple seconds. This is a quick and dirty fix and I haven't had the time to make it work
perfectly, just to make it work. Also, stealthdave, addonscriptorde, and Romans I XVI did most of the work on these; I barely modified it to work for windows so I can't claim much credit.
