I just upgraded from 5.0.4 to 5.0.6 and the drag and drop attachment support appears to be broken. The zimlet appears to be active and listed in my COS but it doesn't work in Firefox. It worked normally before the upgrade. I tried re-deploying the zimlet but it still does work. Is anyone else seeing this issue?
Note: I am not composing on a new window so this is not the problem.
