Welcome to MR!
Please give us your workflow using the "highlighting tool in notes", as to my knowledge, ZORK-Edition doesn't change anything in this code. So the problem may also exist in more recent versions of PRS+
OTOH: uninstall ZORK by
A) install any other version of PRS+
B) run the uninstaller form the
project-page (giving you an stock firmware again)
