Find & Replace problem - previous search / search history no longer working :(

Hello all,

When I use the Find (or Find & Replace) feature, when I click on the little magnifying glass icons next to the Find/Replace text input fields, I no longer get a list of historical search strings that I have used in the past.  When I click on them, nothing happens.

I don't know if this is a recent bug or if I've accidentally turned something off in the settings.  I've dug through the settings but can't find anything relevant to this specifically.  All other "history" related settings I can find are active and set to various numbers.

FYI I'm using PHPStorm 8.0.3 (build PS-139.1348) for OSX (Yosemite 10.10.2)

Any clues?
