Roy RainfordAfter running Mailbox Manager v2.2.7 and trying to quit it, I have an 'Activity' box open on the iMac desktop which I can't close. It says"Getting data from mail No.12". It has been running like that for hours. If I try to shut down the iMac, I get a message box saying, "Mailbox Manager" interrupted shut down. "To continue shutting down, quit Mailbox Manager." I am going round in circles! Help please.
