When using the rotate tool, the angle is in the dialog box (whatever I last used) is automatically applied to my object. If I just try to change the angle it applies that rotation to the new position (based on what I used last), rather than applying the new rotation from the original starting point. I can't even begin to explain what turning preview on and off does, so I included a short screen grab for you. Using Illy version 23.1.1, with MacOS Mojave 10.14.6. I also am using the entire sweet of Astute Graphics plugins.
