Tried this twice, it don't work on my Mac. It corrupts the file and the only way I can restore it is to use my "Time machine" to go back and re-load it..
ON ANOTHE SUBJECT... Last night and right now it takes 58 minutes to download Fritzing and it leaves out many parts files. I can not enter "Blog" from the Fritzing homepage, it just stalled. I have to use email response to get to you.
I think someone is working with the download file (or has messed with it) in the past 24 hours.
