Sorry, last time I used the wrong subject line.

Original text:

Sometimes, xine stops listening to my keyboard input. For instance, if I push ‘g’ to show the GUI, nothing happens. Pushing ‘q’ doesn’t quit.

However, if I right-click to show the menu, xine starts listening to my keyboard input again.

1. How is it losing focus / losing my keyboard input?
2. How can I fix it?
