Pathfinder Minus Front creating mess
No idea what is going on with CC18 (mac osx 11.2.1), but the pathfinder tool is not cooperating.
See attached. Merely trying to use a tool I always use to create transparent lettering (knock out of a background). I use the Minus Front tool on two objects, and this is what I get. Odd, unselectable chunks of the background shape. It's not a redraw error, it persists and shows up when placed in indesign.
Any ideas would be really welcomed. Thanks!
