Bug 335444 Detached windows do not get rendered automatically
I20110125-2200 1. F1 2. Detach the 'Help' view. 3. It has now disappeared. 4. Pressing 'F1' again does nothing. Resetting the perspective doesn't help. Closing and reopening the perspective doesn't help. Restarting doesn't help. If you restart the 'Help' view will appear in a detached window.
