We upgraded recently to 4.1 and the receptionists are now reporting that at least once a day a call comes into the attn console program on their PC and the call control button "freezes" grays out on the Program and they can't answer or trn the call.They shut the program down and restart it and the call is still stuck there.They need to re-boot their machines and re-launch the program to clear the call.Has anyone heard of this problem??Thanks in advance.
