Dual monitor setup: Tool pallets keep jumping to the far left edge of left monitor

[Brad5FFC]

Myself and others I work with have dual monitor set ups. 4K LG monitors. Various Mac computers. Left is main monitor, right monitor is where we keep our pallets. When waking from sleep or restarting, all the pallets have jumped over to the far left side (almost off the screen) of the left (main) monitor. We have tried creating mutiple workspaces, locking workspaces, etc. within each program. This happens in all Adobe programs. Nothing fixes the issue.

I haven't seen this on multiple Macs with dual displays. What is your Spaces setting for treating displays as different Spaces?

[Brad5FFC]

On my computer, I have 3 Spaces on my main (left) monitor. The right monitor is just a single Space. A few years ago, I had the exact same setup but was using Apple Cinema Displays. Never had the issue then. Also, my co-worker has the same 4K LG dual monitor setup but doesn't use Spaces, but still has the exact same issue with pallets jumping to the far left on his main monitor. So, I'm not sure Spaces has anything to do with it.

Hi...Did you ever get this issue resolved? I'm having the same issue right now.

I only have one monitor and my photoshop pallets move and hang off the left edge of the screen after waking from sleep. I use the Essentials Photoshop workspace. I have a DELL S2721QS Display which is 4k. Is this display related?

[Brad5FFC]

Yes! Same thing here. It's very frustrating!

I'm trying this instructions --> Solution 2: Assign the application, such as Photoshop, to All Desktops or None.

So far it seems that if I assign PS to Monitor No.2 it still reverts to Monitor No.1 when I turn off No.2 but it bounced back to No.2. when I turned it on. 

See how it works out for you.
