@AlexG @UlrikeFischer The package author replied to my e-mail: "the files are intact, but they come with the 'clickable' library which allows to click into plots and show the coordinates under the cursor. This clickable library uses Acrobat Forms internally, and these forms result in the "save changes" dialog.
I will see if I can suppress the dialog without disabling the feature."
