Same, ever since the latest update.
Never seen this in 10 years of using ai.

iMac (Retina 5K, 27-inch, Late 2015)
MacOs Monterey 12.2.1

Same issue here

MacBook Pro 13-inch 2019
MacOS Big Sur 11.6
Apple Magic Mouse

Illustrator Version 26.1

Yes, this exact thing, complete with odd green cursor. Started happening after 26.1 update.

I have the same problems since the update to the Illustrator from Creative Cloud, updated this week, both my home Computer & Work computer have this issue.

OS: 11.6.4 (20G417)
iMac: (Retina 5K, 27-inch, 2020)
Processor: 3.8 GHz 8-Core Intel Core i7
Memory: 64 GB 2667 MHz DDR4
Graphics: AMD Radeon Pro 5500 XT 8 GB

Illustrator version: 26.1

This is something that keeps happening to me too, or when I select one object to move illustrator will freeze very briefly and a different object will jump to that position.

Is this cursor common to some function within illustrator on OS X, or is it an OS-level cursor of some kind?

I work on windows and have never seen this at all. Makes me wonder if illustrator's functions are being ignored in favor of some OS-level key combination.

**edit**

I see from this apple support page:
https://support.apple.com/guide/mac-help/pointers-in-macos-mh35695/mac

that this cursor is the OS X "copy" cursor, activated by option-click. I don't think this should be showing up within illustrator.

I have same issues
I have 3 Mac - all same.

Same exact behavior over here as well.

Macbook Pro Retina mid-2014
MacOS Big Sur 11.6.4

I'm experiencing the same exact thing. It also seems like maybe illustrator is treating any drag/move as if ALT is also being held; I'm seeing the little green "+" icon popup when this issue occurs.

Also this glitch seems particularly crazy when dragging/scaling artboards.

I have an iMac and use the magic mouse. Since the most recent update to illustrator, 75% of the time when I drag an object to move it, it returns to where it previously was. This seems to happen if I move my finger on top of the mouse at all when dragging, but it also happens when I make all effort to keep my fingers still and just move the mouse.

Sometimes the object just springs back to its original location but sometimes the green plus sign appears that signifies you're adding an object to a new page, or dragging an external object onto illustrator. This has the same effect in that it just springs back to the original location.

One final note is that when this happens, illustrator counts it as an action, where in the edit dropdown, it allows "Undo Move" but nothing changes

Can't Move Object in Illustrator CC2021 Using Mouse on Windows 10
I dont have Photoshop, this happened after yesterday's update to CC with the latest version

Since starting Illustrator today I can't move any selected items with my mouse. When trying to move objects, Windows 10 makes a problem sound and nothing happens. I can move using arrows but it is incredibly frustrating and time consuming. I am having the same problem when trying to move artboards, but this time there is no PC sound and the artboard moves 50% of the time, by a few px. Each time I try to move something, it flickers. I hadn't made any changes or selected any new tool since the last time I used AI and things worked smoothly. I can't find any fix online, as the only forum mentioning this fixed the problem by closing Ps. I have no other Adobe apps open and I closed and launched AI multiple times now to no avail. I really need help fixing this as I rely on Illustrator to work.

I cant't move object that i draw using pen tools with selection tools..

I am preparing a print data with many pdf vectors and normal vectors in it. At random times, after uploading some pdfs and working on the file, i happen to can't move anything. I click on it and move with arrows on the keyboard but with mouse it won't move. I have to save the work and restart the AI.
Any fix on this?

I am unable to move any object whether it is text or a shape by clicking and dragging it. I can move it by selecting coordinates, using arrow keys and the align buttons. I do not have outlines on. I have tried restarting multiple times.

I am utilizing my mouse to move objects and artboards and it is not working at all. After closing Photoshop, it seemed to work. PLEASE FIX THIS BUG!!!

I WANT TO KNOW WHY.

I have the same problem with updating illustrator version from 2020 to 2021.

having the same issu over and over

I can't move anything, how can I solve this problem?
