Accidental scrolling off the Patient View screen
We have had an ongoing problem where scrolling the mouse wheel while on the Patient View screen will scroll to a new patient screen. If you notice this before making any changes then scrolling back up will get you back to the patient you were editing. If you have made changes to the empty form, try to escape out.
Attempts to fix the bug
I have tried to address this removing the "add record" permission from the form, but this caused another error (can't remember which). I have also tried to take the right away with it being automatically re-enabled somewhere
