case # 018 9255 921
Pathfinder does not function properly in Illustrator CC 2017 on my 4 ghz i7 (late 2015) imac. OSX 10.11.16; AMD Radeon R9 M395 2048 MB, forcing me to fall back and work in old Illustrator CS6.

When I divide two shapes or paths (particularly curves, ellipes etc), the anchor points sometimes move, and paths (curves, angles etc) change. Very sloppy, "kind-of, sort-of" results, with an absolute lack or precision.

CS6 and earlier versions did not have this problem. It is intermittent and unpredictable, but troublesome enough as to render CC 2017 unusable and made me have to revert to using CS6 to finish project.

File size: I am noticing that relartively simple vector that would have been a few KB, maybe a couple hundred KB, are frequently saving at 1 or more MB.

Why are the files so large?

I called this in today, but the level 1 customer support person wasn't very helpful, and Indian accent didn't improve the situation.

I am also having numerous problems with changes in basic interface between CS6 and CC 2017.

The overall effect being that, functionally, CC 2017 is a substantial downgrade from CS6.

Are there any good intros or primers on transitioning and dealing with interface changes?
