It may well be that I am imagining this, but it seems that I am unable to drag and drop a resource onto the bookmark menu in order to bookmark it. As I drag the ESV over to the bookmark menu, the resource opens and resizes to the favourites panel. I am able to drag and drop into folders.

I am pretty sure this works on the PC side (I am unable to check at this moment) and thought it had worked on the Mac side also... Perhaps I am imagining things.
It would be good to have this fixed, regardless.
I am on 4.5b RC2.
