Well, I have learnt not to mess with the Agilent Utility while it is logging. I was trying to flag an event on-the-fly when the program lost contact with the dmm.
Meter locked up, PC locked up. Had to reboot everything!
Still nice that I can log 2 variables at the same time, and it can be done in 2 ways:
1) Using the main start/stop controls at the upper left, the resulting file logs both variables to a single file, or
2) using the individual window's start/stop controls at the lower left logs separate files for each meter.
