SOLVED FOR ME

I hope this works for everyone - but it did work for me.

The issue is not due to it being a second monitor, rather it has to do with Mission Control "Spaces".

This was a two-part solution for me.

Part 1 - in the System Preferences > Mission Control settings, uncheck "Displays have different spaces", then log out.
Part 1.5, I launched After Effects, and was like "yay - it works now, but BOO/Hissssss why can't I use spaces if I want to use AE??" I will explain why I chose Part 2 AFTER Part 2 for you impatient folks...
Part 2 - I went back in and checked the box to allow displays to have their own spaces and rebooted again...

Problem fixed for me. I have spaces, as well as work spaces, as well as right-click whereEVER the hell I want 🙂

After finishing Part 1, I recalled someone else reportedly fixed the problem in 2017 by deleting their personal AE Workspaces/preferences.. and so, I thought... hmmm... I wonder if it just needed to reset its expectations about the coordinates on the screen? because right-click did work SOMEtimes.. just not consistently... and only on certain areas of my screen (like the XY the mouse that it was at was different than what AE thought it was showing)... 

What I find interesting is the defensive posts from Adobe on the topic ("I dunno - Apple apple Apple" is I think the direct quote). Adobe - you were there for me when Apple @%$#ed everyone over with Final Cut X and told me that my thousands of dollars spent on third party tools and software were basically garbage. I thank you for that. Sincerely. 

But you are now blatantly disregarding me (your customer) in equal measure. I remember when you used to call me up once per year asking me to beta test for you. Good times on the QA front, yeah? Remember the good old days when you shipped software that was, by and large, "bullet-proof?"

I will make you a deal - I will beta test your stuff for free again in exchange for some software that isn't a @%$#ing pain in the @%$# making me consistently angry as well as late on my deadlines - because of @%$# software. It's REALLY REALLY BAD. like REALLY BAD. This morning alone - 4 hours spent trying to fix this problem. 

Yesterday, I spent three hours trying to get Adobe Media Encoder to render, finally giving up and exported directly from Premiere, which costs me more time because i cannot work while rendering... thanks for that. Every day it's some new thing I need to figure out a @%$#ing workaround for when the real workaround is right in front of me... but I do not want to do it... the workaround is to go back to Apple because you now hate your customers in the same way Apple did back then.

But since you both appear to hate us equally - I can honestly say that these sorts of issues do not happen with Apple - but I REALLY DO NOT WANT TO LEARN Apple Motion - - that @%$# is more backward than After Effects which says a lot.

Sigh - thanks.. I feel better.

I have just encountered this too, and it is very irritating and slowing me down BIG TIME.

This is a known issue in After Effects (all versions) on macOS High Sierra (10.13) when the After Effects interface is on a secondary monitor.

The problem does not happen when the After Effects interface is on the primary monitor. It does not happen on macOS 10.12 and earlier.

Our apologies about the problem. We are working on a fix for a future update.
