Ver 1.12.1 starts then unresponsive - SOLVED

[KA1LM]

I installed version 1.12.0 with Administrator rights on my Win10 laptop. GPS is connected and has drivers. The setup page starts, displays GPS lat/lon, altitude, time, grid square, instantly; then turns gray. I can not change anything from defaults and the screen says "Not responding". After several popups, status shows laptop clock was synched. Windows Task Manager shows BktTimeSync "Not responding". 
I left it running last night, this morning, the taskbar hidden apps showed the icon, but it disappeared after a minute.
I uninstalled ver 1.12.0 and installed 1.12.1; again with administrator rights, same results.



ANY ideas?
Thanks,
Duane
