In Mail.app Version 9.0 (3054):
- I'm seeing wheel-of-death stalls quite a bit. These feel like they are related to account-check threads blocking the UI
- After every drag & drop manual re-order of accounts in the sidebar, there is a wheel-of-death stall.
- Manual re-order of accounts doesn't stick. After re-starting Mail, the accounts re-sort back to the order they appear in the Preferences:Accounts panel.
Are others seeing these problems as well?
