Script works differently in Mail v5 and v6

Total AppleScript newbie/hack here. Last year I managed to cobble together the following script, which would speak the senders of new messages as they came into Mail.app (as long as Skype wasn’t running).


using terms from application "Mail"
	on perform mail action with messages newMessages
		tell application "System Events" to set theCount to the count of (processes whose name is "Skype")
		if theCount = 0 then
			repeat with newMessage in newMessages
				tell application "Mail"
					set senderName to (extract name from sender of newMessage)
					say "New message from " & senderName
				end tell
			end repeat
		end if
	end perform mail action with messages
end using terms from

In Mail v5 (Lion), if two or more messages came in at the same time, the script worked well - it would speak the sender names one at a time, sequentially.

Now, in Mail v6 from the Mountain Lion GM, if more than one message arrives during a mail check, all the sender names are spoken at the same time, on top of each other, which sounds like a muddled mess.

Is there a simple way to make Mail v6’s behavior match v5? Any thoughts would be appreciated.

Hi,

Mountain Lion is still under NDA. You better ask on https://devforums.apple.com
