I have something similar to this running as a frontscript which will  
report the previously focused object by calling a  
PreviouslyFocusedObject() function. This would work similar to the  
"send in time" technique I'm using now but it means moving the logic  
into a global space rather than within the control that is losing focus.

What I'm hoping to do is determine when the focusedObject is moving  
from a control within a group to a control outside of the group from  
within the focusOut message. What I'm doing is showing a toolbar while  
any object in a particular group has focus. Once focus leaves the  
group the toolbar disappears.  While I have a solution working the  
code could be a little cleaner.
