There are certain default behaviors that one becomes used to when using a computer and Adobe appears to have completely disregarded this with respect to manually entering values! Please fix this serious bug.

When clicking on any modifiable value field, a single click should select the entire contents of the field by default. If I click on the width field in the Illustrator top bar, I should be able to simply type a width and hit tab or enter to apply. THIS IS NOT HOW IT WORKS.

If I see that my width is only off by a small amount that is easily stepped, I should be able to use the up and down arrows (either in the field or on the keyboard) to increment or decrement my value by the next closest whole number in either direction. THIS WORKS CORRECTLY, but only by automatically selecting the entire value THE WAY IT SHOULD WHENEVER YOU CLICK A FIELD VALUE.

If I click a field value and realize that I want to just change the last two numbers or perhaps the current units, I SHOULD CLICK THE FIELD A SECOND TIME WHERE I WANT TO INSERT MY CURSOR AND THE CURSOR SHOULD GO THERE, DESELECTING THE VALUE. Clicking and Dragging across a value should operate in this same way, CLICKHOLD where you want to insert the cursor and drag to SELECT THE VALUE TO CHANGE. This makes sense because the CLICK-HOLD action is really CLICK CLICK-DRAG.

Currently, I click a field value and think that I can quickly change the value to 50px, so I type 50px and press ENTER (only to get an error that 1050px pt is not a valid value--a total bust to my workflow. So I click the field again and have to use CTRL-A to select the entire contents of the field in order to type the new value. THIS SHOULD BE BY DEFAULT.

CLICKING A FIELD, like tabbing into the field, SELECTS THE ENTIRE CONTENTS. CLICKING A SECOND TIME PLACES THE CURSOR AND DESELECTS CONTENT. CLICK AND HOLD OR CLICK+DRAG SHOULD OPERATE LIKE DOUBLECLICK

This is common sense and Adobe is the only software package on the market that handles this in this peculiar way. Please fix it.

P.S. And here's the deal: when I enter a value and press tab, if I haven't explicitly declared units, use the previously assigned units. Don't complain that I didn't have the right units. I can't tell you how many times I have entered 50% in the width field just to be told that 2150%80px is not a valid entry.

P.P.S. It is terribly inappropriate and completely unhelpful to click an item and be told that it is 100% wide....That makes no sense. Percentages are always relative in context. If you say it's 100% wide, you have to say relative to what? It's original size? the window size? It's parent size? Width and heights should not be presented in % by default. Always use the current units (px, cm, mm, etc). and if you wan to add a "transformed" width or height (to the TRANSFORM PANEL), you need a Context field that indicates what the percentage is applied to. This would be great if you wanted to make a shape with 4 identical columns...you would draw the parent shape, then enter isolation mode to add 4 columns, each of which was 25% wide 100% tall given the context of their PARENT. THen later, when the item is broken apart, the height and width are only available in the current preferred units, not %.

1. 21.1.0 (macOS sierra v10.12.6 (16G29))

2. This is happening more and more, and usually when first opening the application. If some dialog box, typically a warning or something, pops up but for some reason then gets pushed behind or hidden by the main app window, there is no way to get back to it and no way for the app to function. Trying to click on ANY part of the app just gets the "no - beep", the sound that plays when you are trying to do something but something else has to happen first... like if a warning box pops up and you try to click ANYWHERE on the app, it will beep at you until you accept/cancel the warning, THEN you can operate the app as normal.

BUT, when this box becomes hidden or is just behind the app, nothing can get you back to it. You can't minimize the app because it just beeps at you, waiting for you to respond to the warning. You can CMD+Tab to other apps, but when you get back to Illustrator, it doesn't refresh of bring the warning box back.

On the dock icon, there is a "Show all windows" option, but that doesn't fix the problem either.

On the Menu Bar > Illustrator > Quit is grey-ed out, the Dock Icon "Quit" doesn't work, so all you can do is open the Activity Monitor and FORCE QUIT Illustrator. Then, reopen and hope it doesn't happen again.

PLEASE fix this
