2.2.2 still crashing

Version 2.2 had worked worked on my system (Mac Pro tower OS X 10.9.5) until recently, but recently the app crashes any time I try to select another target drive. Works fine on startup disk. So, installed 2.2.2. Works fine on startup disk, but immediately crashes when attempting to select another target disk.
