+Compatibility with Flash full-screen mode
+-----------------------------------------
+
+The official Flash plugin (flashplugin-nonfree) can open full-screen
+windows.  Version 9 has a bug in this feature which causes these windows
+to close immediately if they are managed by Ion3.  This package includes
+a workaround, but it is ugly and is not enabled by default.  If you
+need it, add this to cfg_ion.lua:
