Hi, This is my problems. I have some for years and some are new but it's a lot worse since v67. Problems i have : '''* Folder don't show unread messages (folder name should be bold and display number of unread).''' The only way i found to fix this is to click on each folder one by one, or sometimes fix it (in properties window). Before v67 it occured each time i tried to search in messages accross many or all folders. Now it occur very often. '''* Messages list ordering in a folder is lost (revert to date ASC).''' Before v67 it occured each time i tried to search in messages accross many or all folders. Now it occur very often. '''* Folder don't display messages list in messages pane. It display nothing or same things as if i click on an account.''' Sometimes i click on another folder then i come back and it solve problem, sometimes not. Fix folder don't solve. This problem is now regular and much worse since v67. '''* Messages are not filtered to folder with previous problem.''' This problem is now regular and much worse since v67. Fix i tried : # Start in safe mod : Solved nothing. # Fix folder in properties : Sometime it fix sometime not. # Delete index files : Sometime it fixed before v67. Not retried since v67. # Delete lot of old messages to lighten DB : Fixed some problems but not for long. Important information : I have hundreds of folders and filters. Perhaps it play a role in this problem. It's really a great pain to work like this. If someone have a real and definitive solution it would be great. Regards.
