Currently, the eLog doesn't update if in the background/minimized/ect. I assume this is from a performance rationing point of view. However, if you minimize the eLog and then someone makes a note, there's no way to tell the note was made when you minimize the window.
In the current (read: old) eLog the Current/Update button serves this purpose, with it turning yellow when there is an update available. One could preform similar constant polling in the background and change the refresh image/text/ect.
