My Outlook window, divided in two columns, has the left listing all the folders and the right showing the content of the selected folder.
When selecting a new folder I click on it in the left column and that makes the letters naming the folder expand to a new larger size that cannot be accommodated in the space reserved for description.
It is not always the program acts like this, but each time it happens I have to shut down and open again to reset.

What is happening and what can I do to avoid it?
