When ever I get a text message it stalls.

I have it configured to 'create chats from message'. If I have an existing string it feels like a real long time for the radio to retrieve the string and create it into 'chat' form.

I've always used this feature but lately it seems to lag big time, even if the 'chat; string is only 1 or 2 messages long.

Am I doing something odd? Wrong/conflicting setting somewhere?
