I've only just noticed that an object's duration as shown in the Size/Position dialog is rounded to the nearest second. Any obvious reason why it can't show frames or ms too, like the Properties window?
Or for readable quality: https://dl.dropboxusercontent.com/u/4019461/MEP-ObjectLength-1.jpg
Edit: Also, I've discovered that if you click in the duration box, it changes from say 6s to the more accurate time of 5.8, close to the 5.840 shown in Properties.
There's no shortage of space to show the full precision, making the two displays identical!
