BarbaraB of Deep South Embroidery mentioned selecting the USB port for the dongle. Hope this helps, since either I pay for ANOTHER overhaul on my COMPAQ laptop due to viruses which may not correct the issue of the screen going black while working. It will not respond and reappear, I have to shut off and turn back on. I'd love to hear from more users who run Amaya OS & DS on iMac. =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
