[MlMt] All mailboxes formatted as "Sent Items" (unable to disable "To" column)

[Christian Bailey]

All my mailboxes, including Inboxes are now permanently treated as "Sent Items”. They all show a “To” column, which I’m unable to disable. “Revert to default columns” is greyed out.

I already tried quitting and running in Terminal:
defaults delete com.freron.MailMate MmMailboxRelatedStates

I tried deleting the Test release and rolling back to the Beta (r5918).

I had been seeing more and more problems with default columns not being honored (e.g., always reset in Smart Folders, always reset in search views). But now this latest issue has made MailMate totally unusable.

Since rolling back to the Beta, I’m also experiencing MailMate hanging for ~10seconds every time I compose a new message or reply to one.

Can anyone offer any suggestions?

Thank you!
Christian
