Editing and archiving comments on tracking board.

Under the comments section of the tracking board, the edit function is not working. The 3 blue dots appear but when we click nothing happens. I am trying to edit my own comment. Also can it be changed where other nurses can edit someone else's comment. Example, we would put Vital signs Q 2 hours to remind staff but this order can change during the admission to Q4 or Q shift. We want to be able to edit this, not just the nurse who put it in.
