so a few days ago the diablo 3 launcher had an update. went well, played. then yesterday when i clicked on the diablo 3 icon on my taskbar, the diablo 3 launcher made an update again. i passed on the thought since i really can't do anything about it and waited the update to finish the second time.

then to today i just clicked the d3 icon again and it made another update! i asked my friend when i logged in-game and said he didn't get another set of blizz launcher update like i did. is this a bug? will this keep on happening? this is harmful for the program installed? is there a "cure" or a fix for this?
