How do I stop Thunderbird from marking email as read just because it was highlighted in the list for a few seconds

When I'm looking through little used mailboxes to see just what I want to delete Thunderbird starts marking any line the highlight rests on as being read. Somehow I think I got rid of this on my main email when I first set it up but cannot for the life of me remember how and I cannot find how.

Chosen solution

Is the Options > Advanced panel > Display panel - Advanced tab - Automatically mark messages as read setting still correct?

I think I figured it out quite by accident. It seems to do this if there is any part of the preview section at the bottom of my screen. I pulled it down all they way (not to show the preview but just the list) and it SEEMS to have solved the problem!
