Why Does Mail Keep Showing an Empty New Email Message?
Every once in a while I'll notice this in my dock:
A mail message, apparently, that, if I click on it, it shows an empty new message. Usually I can get rid of it by closing it, but sometimes it displays "Loading..." in the centre and I can't close it no matter how long I wait. The only way to get rid of it is to reboot.
I'm using a Mac mini 2018 running Sonoma 14.6.1.
