JabRef version 3.6 on Mac OS X 10.11.6

Steps to reproduce:

1. Typing a string to be searched into the search field on the top left of the window.
2. At the same time, the entry editor (at the bottom) is open.
3. Problem: Sometimes (didn't find the pattern) the text-cursor jumps away from the search field into one of the slots of the entry editor. From that point on, typing happens not in the search field but in the slot of the entry editor. This can cause retyping (so: deletion and then typing) of some of the information within the entry editor. (Luckily, this can undone by the Undo command.)

Essentially, this problem makes me search only when the entry editor is closed/deactivated. Pretty annoying.
