Francisco,
Thanks for the links.
Exactly what I experienced.
But, Reset Adjustments on All Selected Variants seems to solve the problem.
I'm running C1 10.2 - Build 10.2.0.74
If I go to Updates, there is no option to download a version 10.2.1 only version 11.0, which I don't want to upgrade to.
Worst case scenario, I will save out the TIFFs before closing the program.
I have submitted a Support ticket. Let's see what happens.
Thanks.
D.
