--- Comment #8 from Timothy t_arceri@yahoo.com.au --- The Marco patch fixes most of the problems, however it still doesn't work 100% correctly.
When using alt+enter to fullscreen the application fullscreens but then it loses focus and you end up back at the desktop where you need to re-select the application from the taskbar.
