Hello, I'm testing the commercial version of Ham Radio Deluxe. I'm using it with a Yaesu FT-450D via a USB to serial bridge (COM5 on my setup). It performs fine until I attempt to close HRD Rig Control. When it gets to closing the COM Port it hangs, with a small pop up indicating "Closing... (Not Responding) with the blue progress bar stalled. This results in me having to force the program closed. If I try to re-run the program it tells me that the COM Port is in use, obviously because it never was released due to the abnormal termination of the software. I've searched the interwebs and come up empty. My registration at HRD's forums is pending so can't ask there yet. I'm stumped. I'm also happy I'm on the 30 day trial as no solution for this would be a deal-killer. My #1 suspicion would be the USB to serial bridge but aside from this issue it seems to work flawlessly. Any thoughts would be appreciated, with thanks in advance. 73.
