Thank you P Spier. Uninstalled InDesign CC 2014, re-installed InDesign CC 2014, opened without third-party plugins, and with brand new preferences... it still crashes on close.
P Spier, for clarification, please describe for me what you mean by "widgets," and why you intuitively sense this! I don't think InDesign uses widgets, or is it possible your are refering to my system (Mac OS X 10.10.2)
Thank you.
