I know it's only a workaround and not a solution, but at least until 
you're able to get the rodent behaving the way you like, you can change 
the setting in Thunderbird preferences.

In v1.5:
Edit --> Preferences --> Advanced
[Check box]  Wait XX seconds before marking a message as read
(2nd item down)

Make it 5 or 10 seconds and at least you won't have to worry about a 
message being marked as read because your mouse inadvertently lands on 
the header.
