Upgrade to El Capitan Mail freezes when left open for a period of time and not used.
Every morning the Mail if I leave it open overnight, the spinning wheel rotates and nothing opens or can be used.I have to close it by force quit and then reopen it.Not the end of the world but It should not act that way and it concerns me that it creates other unseen issues.After I open it new mail then begins to download.
Not sure this is the right section, if not please advise,
