We have been running parallels successfully for our business for 5 years. With the recent upgrade to Mavericks and parallels 9 my Camera Control Pro program suddenly crashes mid photo. This has worked for the last 5 years successfully in parallels. At first I thought no problem, I started up our clone of the windows in case this was a corrupt file. No such luck, and on a full second brand new computer it has the same problem. It might make it impossible for me to run parallels anymore in my business which is over 20 PC's. Any ideas as to why the USB suddenly disconnects and I loose the photo? I am an optometrist and it is retinal photographs but taken with a Nikon D200 camera?
