Hi,
i do not know if it's bug or problem with configuration...
i'm using kmail and have several folder and filters, which filter my mails by some criterias and place them in correct folder. the problem is, that some of my folders are somehow "broken". the main problem is that i can't use "next/previous unread mail" shortcuts (and buttons) in them. buttons are grayed out and shortcuts do nothing. i still can read my mails with spacebar (and jump to next unread at the end). i've also discovered, that the "broken" folders have some options inactive.

here is the screenshot with "broken" folder:

and here's with a "good" one:

PS: i'm using version 4.8.1

I vaguely remember something like this, but I'm not sure if it was fixed in 4.8.2. Once your distro offers the option, try to upgrade and report back.

ok - i've just upgraded to 4.8.2 and it seems to work again;)

If it's solved for you, please mark this topic as solved, thanks!
