Possible bug in L4Mac?
When I start typing a term in the search box, a set of suggestions begins to appear below the search box. If I scroll down to the term I'm looking for with the keyboard and press 'Enter', it does not select the term. Instead, it takes whatever is currently in the search box itself. For example, in basic search, begin typing "manic". When you see Manichaeism, move the selection with the down arrow on the keyboard and press 'enter'. On my system, it searches for "manic" instead of "Manichaeism".
If you make the selection with the mouse, it does work correctly.
