When I have the modal up to move funds from one category to another, if I click "Move", the modal doesn't disappear immediately, and sometimes it takes long enough for the "operation successful" notification to appear that I think my click didn't register, so I click again. (I often have trouble with mice interpreting a single click as either multiple clicks or no click at all, so a click not registering isn't too far-fetched.) If I do so, however, the requested move goes through as many times as I clicked, instead of the one time I expected.
