I've been using v2061 but decided to give v2088 a try due to the new enhancements.
One issue I ran across immediately is if you change the target gamut in the middle of measuring a sequence, the stab patch will pop up on screen immediately, taking the place of the intended patch in the sequence, and the stab patch will be measured. This is when using a PGenerator.
With v2061, I can switch target gamuts on the fly with no ill effects.
Is this new behavior intentional?

Oooh!
Good spot.
We'll get that looked into.
