With Acrobat we can select one of these annotations and run a simple javascript in the console to unlock the annotation. Sure enough, if the tool is locked and the default properties are set to the locked state, there doesn't seem to be any way to change this setting manually. I attempted to recreate this scenario to see what would happen.

It could be a glitch in the software or it could simply be that they received a PDF with a locked annotation and accidentally (or purposely without realizing what would happen) selected "Make Current Properties Default". How it came to be locked for these frustrated users remains a mystery. With this particular tool the "locked" check box in the properties window is perpetually disabled, so it can't be unlocked manually, nor can it be locked in the first place without using javascript. Once an annotation is locked it can't be moved, resized, deleted, or changed in any way. If the default is locked the tool ceases to function except for adding empty and locked Typewriter tool annotations. My original theory was that somehow the tool had been locked and the default properties were accidentally set to match the locked state.

In fact, one of the respondents was advised to uninstall and reinstall Acrobat to fix it. When I read through additional comments posted between then and now I realized that this is a common, and very frustrating problem. I didn't think anything more about it until somebody else commented on the very same question today. I took a guess at what could have gone wrong and my answer was voted as the best answer. The above quote is part of a question I answered 517 days ago on. It cannot be deleted either, despite it having no text." I click once and the box appears and the Comments List shows it as being added & locked with the padlock icon. "The Comments Annotations (Typewritten Text) is always locked I can't write anything in the box, it cannot be resized, etc.
