Xseries :: Message Editor Already In Use?

when ever i'm trying to send msg's to more than 5 ppl and i click send it always says message editor already in use and if i press send button again it sends blank msgs to all ppl double , i have delete than msg and then go to outbox defer all msg's from sending and click on them and click send again.i tried switching off , restart ,msg editor is not open previously i doubled checked it , it just says msg editor in use while in background the msg's are just stuck in outbox u need to delete the current msg which when u clicked send said editior in use , delete it to get out from that write msg section then go to outbox click on every msg defer then send againand instead of clicking delete to get out if i click send again it send blank msg twice?
