new mail not seen in open inbox pane but number behind folder in folder tree does increase

I have my inbox open and a new email arrives. The number between brackets behind the inbox folder on the left side tree of folders, increases with 1. However, I do not see the new message in the inbox pane. When I first open another folder, and then return to my inbox, the new message does show up as it should in bold. So I have to change folders all the time before I can read new messages that are indicated by a number increase in the tree.

This was not the case before, and it is very irritating. Any suggestions?

Thank you!

THis sounds like what we are seeing caused by the Calendar addon.

For Windows, 1. install older version from http://releases.mozilla.org/pub/mozilla.org/thunderbird/releases/38.2.0/win32/en-US/Thunderbird%20Setup%2038.2.0.exe 2. remove calendar addon, restart thunderbird 3. update thunderbird at help | About 4. reinstall calendar addon

Does that help?
