->  	I've been playing with Focus policy a lot (trying to get SOMETHING
->  similar to what I use under FVWM2) and noticed this problem.  It has
->  NEVER occured for me when in CLICK_TO_FOCUS.  It appears to be under
->  SLOPPY focus, but I was switching back and forth when it blew, so it's
->  hard to tell for sure.  When it happened, it seemed that I would lose
->  control of an existing window when I openned up a new xterm.
->  
->  	Next point on the curve...  I found that I COULD return keyboard
->  focus to the "dead" windows by switching to CLICK_TO_FOCUS and clicking
->  on the title bar.  The title bar did not change highlight, but the cursor
->  in the xterm window changed and I could type into the window.  If I typed
->  "exit", the xterm went away but the window stayed (solid black) and the
->  window decorations remained (but none of the buttons on the window
->  decorations responded to any mouse clicks).
->  
->  	I also found I could not "raise" a window over one of the dead
->  windows.
->  
->  	When it started happening, I switched to CLICK_TO_FOCUS and
->  I didn't loose a single window after that.
->  
->  	I'm working on narrowing down the conditions under which this
->  occures to help repo it...
->  
->  	BTW...  This is on a Linux system (RedHat 5.2 Linux 2.2.0) with
->  enlightenment from the cvs tree.
->  
->  	On the subject of FOCUS policy...  My preferred FOCUS policy is
->  CLICK_TO_FOCUS.  Under FVWM2, clicking anywhere in a target window will
->  change focus and then raise the window to the top.  (Is this what
->  RAISE_WINDOW_ON_NEXT_FOCUS is suppose to do?)  Enlightenment will only

yup.

->  switch focus and raise the window if I click on the window decorations.
->  That can get to be a problem if the decorations are hidden by other
->  windows.  Sometimes, it seems like it won't raise the window unless I

click to focus shoudl work just by clickign anywhere in the client
window.. not just decorations

->  specifically click on the title bar, clicking on the sides or resize
->  handles don't raise the window.  I'm not quite sure what causes that.
->  I'm guessing that I'm largely missing the correct combination of control
->  parameters to do what I want to do.
