Thanks for this detailed report, Emile. Take a look at this message: https://www.mail-archive.com/search?l=mid&q=20180228110424.6160469.4449.14790%40web.de If you follow the instructions there (disabling the virus scanner, if you feel comfortable enough to do so), does it then work? I do not know why this is different from rc2. I hope we can figure that out. Scott
