For those that run into a lost communications drop down window once in awhile when calling for a compile and program. This started out as a 50% fail to program to a 100% fail. I had been running the and programmer through a powered and fully loaded 7 port USB hub. I pulled the USB programming cable from the hub port and went directly to a USB port on the laptop. Now no problems. I don't know if cable lengths or loading or ?, anyway problem gone.
