Good afternoon. I am using Franson GpsGate v220.127.116.113. On my tablet I have access two GPS devices. One is via UDP streaming from the wifi connection, and the second is a built in u-blox gps. The UDP streaming wifi works great using the franson UDP receiver. When I switch to the internal GPS (COM5) it seems to behave normally and detects the GPS data. However when I try to "close" the port to switch back to the UDP stream GPS Gate locks up and goes into not responding mode. Any ideas what would cause this? I have removed and reinstalled the product several times. Thank you!
