focus weirdness

["Christopher T. Lansdown" <lansdoct screech cs alfred edu>]

Hi,
	I'm trying to get an entry box to select its contents upon recieving
focus (in this case it is actually warranted).  This is the code that I'm
using:

$entry->signal_connect('focus_in_event', sub {$_[0]->select_region(0, 4);},
$entry);

(in perl $_[0] is the first argument, and the bindings make all of these
things objects so that the widget argument can be omitted).

It doesn't work when someone clicks in the entry box (though it does get
called, I've verified this with print statements).  It works, however, if I
give focus to an entirely different toplevel window and back, it does work. 
Am I going about this the wrong way?  Am I encountering a bug?  What is the
best way to do this?  Thanks.
	-Chris
