fillable fields aren't highlighted

[charlesn46625504]

Why don't my fillable fields show as highlighted any more?

Acrobat/Reader DC don't include the Highlight Existing Fields button in the document message bar as previous versions did, but you can turn field highlighting on by selecting the following user preference: Edit > Preferences > Forms > Highlight Color > Show border hover color for fields

This is used to control field highlighting, despite the incomplete description.

The menu preference is unreliable. If you open a Reader-enabled XFA form and then toggle the option,  the fields will stay highlighted/hidden until modified.

Happens on Windows 10.

If you're into batch script you can add a checkbox menu to toggle it from the menu. Set app.runtimeHighlight to true, like

app.addMenuItem( {cName:"menuToggle", cUser: "&Toggle highlight", cParent:

    "File", cExec:"app.runtimeHighlight=!app.runtimeHighlight;", 

    cMarked:"event.rc=app.runtimeHighlight",    nPos: 8});
