duplicate of bug 10213?
Different version of Pegasus Mail but the problem is essentially identical. Wine shuts the program down when a message is sent or the editor window is closed. This seems to be a normal shutdown in but cases since the lock file is removed as in done with a normal close. If the program crashed the lock file would remain.
