"Working" preventing an end user from typing on a form?

We have an end user who is complaining that the "Working" message keeps coming up while typing in a form field, and that she "cannot continue until Working goes away on each field".

In my own testing, this form never shows the "Working" message - there is nothing supposed to be happening while typing into the fields. Why might this be occurring, and how could we resolve this for the user? Does anyone have advice on troubleshooting this?
