Refresh Entourage 2008 Draft Window

I am working with Entourage 2008. I am trying to programatically add an email address to the BCC field of a draft message. Here’s the code I have so far:

tell application "Microsoft Entourage"
	
	if class of window 1 is draft window then
		set theWindow to window 1
	else
		beep
		display dialog "You must have a new message window open to use this command" buttons {"OK"} default button "OK" with icon 0
		return
	end if

	set BCC recipients of theWindow to "WaitingFor"
		
end tell

The good news is that the script works. The contact (i.e., “WaitingFor”) is entered into the BCC field. However, the BCC is not displayed, so that I can get a visual confirmation. How can I do that?

Thanks.

Model: MacBook Pro 2.4 GHz
AppleScript: 2.0
Browser: Safari 523.10.6
Operating System: Mac OS X (10.5)

I think I have tried virtually everything, including screenupdating. The only thing I can get to work is to save the window. That seems to refresh the screen:

tell application "Microsoft Entourage"
	
	if class of window 1 is draft window then
		set theWindow to window 1
	else
		beep
		display dialog "You must have a new message window open to use this command" buttons {"OK"} default button "OK" with icon 0
		return
	end if
	
	set BCC recipients of theWindow to "WaitingFor"
	
	-- this refreshs the window
	save theWindow
	
end tell

This works, but it seems like a cludge.
