 Andy, is the argo calibration really changing or is the frequency scale just shifting?

Thanks for the reply Garry.. In my case, it seems to be the actual calibration.. 
I use 540 Hz for FC, and center it in the window.. Today when I opened, and started
ARGO to look for " MP " ; 540 Hz was centered, but " MP " was showing at 544 Hz,
when it should have been 540.5 Hz.. The frequency scale never moves, but the signal
does ... Now on a coincidental note.. The random frequency shifts do seem to be 
more notable if I am multi-tasking on the computer while running ARGO.. 
There may very well be a correlation to that..
