Hi,

I'm on build #4508 now but there is still a weird problem. I always make 
sure my Keychain contains the correct passwords. But somehow, if I 
reboot MailMate, it updates the Keychain password with the old initial 
password of my accounts. I really don't know where MailMate finds this 
old password and why it happens. But it's pretty annoying. Rebooting 
MailMate means password errors, logging in 1Password and save them 
again. Works for that session but MailMate will update the keys wrongly 
in a reboot.

Regards,

Bram
