Duplicating objects in Illustrator CC 2017 only works on occasion, it is not consistent as it was in previous versions. Holding Shift to align while dragging and duplicating also doesn't work. These were both key features of Illustrator and if there is a way to fix this problem I would be very interested to know how!

Center point (set in Attributes palette with 'Show Center' button which is default for Live Rectangle and Ellipses) becomes invisible when you drag an object. And because I often use center to match position to certain point on a grid, I cant properly position object and get angry.
Hulk illustrate!
Please see animation attached for clarification.

when the zoom-level is 14800% and higher I'm unable to select or move the guides

When I do right click, coordinate of context menu location doesn't double and located at the center between of cursor and top left corner of the workspace. This bug happens at all CC versions support Hi-dpi displays. Absolutely clean Windows, Illustrator, no plugins.

This problem only seems to happen in Illustrator. I have not seen this issue when I use Photoshop.

Clicking with the mouse, does not always work as expected. It is almost like there is a long delay before the release is detected, resulting in a drag operation. Sometimes I see the spinner appear after I click. I have tried a different mouse, same issue. In the video, I am only ever doing a quick click, without moving the mouse.

Fix "Display Measurement Labels" so that it works because it doesn't respect the setting.

Hi,

I am having a problem with illustrator since a few days now and I just don't find solution for it.
Every time I open Illustrator it forgets that the control area, the tools area and the other effects and tools area such as, transparency, layers, colors etc was opened. It is really annoying to open them every time.
Could someone give a solution. And, I am using the latest version of Illustrator for 2 months now I think, and it started to do this only a few days ago.

Illustrator 22.1, Max OSX High Sierra 10.13.3

The smart guides are always a little off, unless I zoom a lot.

For example, when I want to cut a path at an intersection, with CC2018, the cut is always a little off.

It happens with many other actions: moving anchor points, clicking on a path end point to continue drawing, adjusting tangents... the smart guides show the correct point, but the action snaps to something else.

See the example below, where I'm trying to continue that red line.

All units are set to 'px'.
Appearance stroke width dropdown says 'mm'.
Stroke same dropdown says 'px' all right.

Transform W: and H: using Arrow keys works only a single keypress. After one keypress illustrator start moving the object. See .Gif

Reproduce:
1 create object
2 select object
3 click in the number of the W of H in the transform panel
4 press arrow up / down on the keyboard
5 press again.

Expected behaviour:
- For the object to scale up every press of the an arrow key.

Observed behaviour:
- First keypress the object scales/resizes
- Second keypress it start moving.

Annoying tutorial tooltip persists even after restarting illustrator. Clicked on the button it's referring to, still won't go away. Hides the navigation bar so you can't even move the document...

See image attached.
Here and everywhere baselines in control panel captions must match.

70% of the times I used to use Illustrator CC 2017 my cursor used to flicker extremely fast switching from the tool I have selected to the default black pointer. With CC 2018 looks like it's 100% of the times.
It's very annoying especially when I have to make accurate selections.

Cannot get Open Documents as Tabs to work. If more than one document is open how can I switch between documents.

In Illustrator CC 2018 (Windows), the Properties panel does not scale in width, so it can not be grouped with other panels (when switching, all panels become equal to the Properties panel in width).

In the transformation section of the object in the Properties panel, you can not change the size proportionally using the Ctrl + Enter shortcut. In the Transformation panel, you can do this.

The action cannot complete because a parameter is invalid.
(possibly a program error) ......... this is what i get when trying to merge layers.

Layer Panel went blank randomly in a multi-layered project. Cannot view titles or any icons. Sometimes running the mouse over layer panel reveals the information that the mouse points at, however, only to disappear (title info, icons etc) if you click on layer.

Latest version of Illustrator CC 2018. Have rebooted system twice, one shutdown for several hours, one restart. Also researching online to find similar issues. Seems to be relatively new issue.
