Thanks David,
As far as I can see, PreCal does not disable it. It is easy to check:
Start OptiCal, select PreCal from the menu. Step through the PreCal
program until it is measuring the guns. Now click in the OptiCal window
and toggle the "Calibration" on or off. Go back to PreCal and remeasure
the guns. The gun values change drastically so the calibration is not
disabled. That is apparently why Craig I and others have run out of
adjustment range on the monitor.

I fail to understand why it would take significantly longer time to save
a few data points when the data is taken the first time instead of
having to remeasure the data again. Saving data takes microseconds,
remeasuering a calibration/profile is many minutes.

I am looking forward to the next version. It will avoid a lot of
confusion. In the meantime, thank you for helping out.
Bertho
