Interactive PDF_drop-down list button moving upon clicking
We're testing an interactive PDF and it seems to work fine for everybody except one person who's experiencing the problem below with the buttons for drop-down lists:
- clicked on the first two items above – all fine
- clicked on the remaining items – had to click twice but all lists displayed in correct place until…
- the last item – appeared on second click on the other page
- after that, all boxes appeared on the other page regardless of whether they appeared in the correct place previously or not.
Screenshot below - the box that is supposed to be in the bottom right moved to bottom left for some reason. Anyone knows what the problem mights be - is it with the PDF itself or the person's computer/version of Adobe Reader? Any suggestions for fixes?

Many thanks 🙂
