Sent to bugzilla, and to this email addy, as per winehq instructions:
http://www.pmail.com/downloads_maine_t.htm
Version to look at is 4.41, a free download.
This email app does a normal shutdown whenever the editor is closed, e.g., after a new email is sent. This is not normal behaviour. In Windows the app stays open, so that one can continue sending, receiving, reading, writing email, etc.
In old versions of wine, this error doesn't happen, (ver. 20050830). The regression error occurs as early as 0.9.20. Based on posts to the wine appdb for this app, it is likely that the regression error ocurred >=0.9.14.
The editor in Pmail was not written by the developer and maintainer, David Harris, but rather licensed by him. Recent wine code seems to interpret an ordinary call to close the editor as a call to close the program itself.
When Pmail starts, a 0 byte file, mailbox.lck is created in the mail box of the user. When the user closes the program normally, this file is deleted.
Since the shutdown regression error deletes the lock file, I conclude the call to close the editor is being misinterpreted by wine as a call to shutdown Pmail.

p.s. - I'm new at this, please forgive me if my report is funky. I did check bugzilla and didn't find anything relevant.
