Why does my T-Bird keep showing read messages as 'unread' even after recatagorizing them repeatedly?

more options

Running T-Bird 24.4.0 on Win 7 PC.

I have several 'bugs' to address.

1) Although I've transferred thousands of old e-mails to 'Achieves', have 'compacted' every file repeatedly [see: Unable to write the email to the mailbox'], I still get the 'Unable to write...' error message requiring me to <Enter> for each individual message to download the bulk of my e-mail from my Yahoo!' mailbox.

2) Regardless of how many times I've recategorized my saved e-mail to 'read', they continue to come up, randomly, as 'unread' every time I open T-Bird.

3) Regardless of how often I select <View>, <Sort by>, <Descending>, my mail keeps being displayed in 'Ascending' order.

I have many thousands (10 yrs +) of saved e-mail in my system (my T-Bird backup folder is 11.6 GB).

Any and all replies will be much appreciated.

3) sounds like CCleaner deleting the session.json file in a misguided attempt at privacy protection.

2) Is this an IMAP or POP account. Does right clicking the folder, selecting properties and then repair change their state?

1) Try windows safe mode. Unable to write to the file is quite lkely your anti virus trying to scan it at the same time.

Would doubt CCleaner involved. Doesn't run continuously and I only run it about once a month. Tried 'repair state' didn't see any changes. Have been fighting the 'Unable to write...' issue over a year. Have read many pages regarding it (http://forums.mozillazine.org/viewtopic.php?f=39&t=1760715

Sorry, that list I put up above doesn't reflect the pages I've reviewed for this problem.
