A USB GPS is connected to my win 10 computer via a virtual COM-port 6 and the NEMA data is directed to the Win10 -sensor. using the popular GPS Direct Com to Sensor driver.  The NENA data can be correctly seen on the COM port and the sensor data has been verified using Microsoft's GPS sensor app.  Ifly GPS reports the altitude and location correctly but the Ground speed remains at 0 kt and the Track remains at 000 deg while in motion in any direction.  Occasionally the GPS Status is reduced to one bar yet the signal remains strong.  Has anyone been successful running Ifly GPS on a WIn 10 computer with an external GPS receiver?

Windows 10 treats an external GPS differently than earlier Windows versions.  It tries to interpret the NMEA data directly from the serial port and provide apps with "location services", much like iOS.  So I expect an issue with the GPS or drivers.  If you send your latest log file to our support team (found in C:\_iFlyGPS_Data\User\#Logs ), maybe that will give us some clues.
