BktTimeSync 1.6.1 locks up, cannot open from Systray

[W6DTW]

I have been having trouble with the latest version 1.6.1.

BktTimeSync will eventually lock up and stop syncing time. At that point the app can no longer be accessed via right-click of the Systray icon. This happens when I'm in GPS-only or GPS+NTP config.

After the crash if I force quit Bkt from the process manager and relaunch, trying to turn off NTP and sync only to GPS time results in a rapid-fire succession of Systray notification messages. As in the other lock up, the Systray icon then becomes unresponsive. I can regain control of the PC by force quit of the process, but a reboot of the PC is required to regain ability to use GPS.

My setup:
ASUS EeePC running Windows 7 with latest patches
Garmin 18x USB GPS puck
Franson GPSGate Server
BktTimeSync 1.6.1

I activated Diagnostic Logging and was able to capture the post-relaunch glitch; that log is attached. I will continue to log and will post the unattended lock-up logfile once it happens.

Sorry should have said Franson GPSGate CLIENT.

Here's the diagnostic log from an unattended crash. The time sync ran for about 80 minutes before failing.

I'm going to disable the GPS sync and just run straight NTP for a while to see if I can localize this.

Could it be that lose connection with the GPS.
