Not sure either. Since I upgraded to 184.108.40.206 (rel 81) I have not had any significant problems. The only issues I have had are: 1) DM 4.5 & 4.6 trying to update - 4.5 Core Apps, Basque language and Password keeper every time I connect to DM, 2) the Device Switch Wizard (I use this to back up my 3rd party apps) does not see any 3rd party apps installed prior to 3 weeks ago and 3) the folders icons are missing even after loading the media file.
