In the updated Patient Search window, there is a hover feature that pops up the content of the field your cursor is over. (Similar to HTML Alt Text.)
Unfortunately, sometimes this appears to "eat" clicks, so it's a little more frustrating to select a patient from the list. E.g., you'll double-click to open a patient but the first click will simply dismiss the hover element. If the hover element could be removed, delayed, or moved off the line itself, or reserved only for fields whose entire contents are not already visible, this would reduce frustration.
