Since one of 8.5 version, I am not able to open record of Mailbox. I tried from this place:
Modules >> Technics >> Settings >> Mailboxes

When I select (one click) a Mailbox -it is not highlighted, after this click can't also open Properties of "probably selected mailbox".
Double-click: don't open the view with mails in this mailbox.

Is there new way to have access both to change properties and view somone's mailbox?
