Dear Anders and Joel, Thank you both.
Just to add one more piece of data. To try to isolate what might cause Lyx to freeze for me but not for you, I booted in "safe mode", so my system would be running only the bare essentials. Lyx behaved exactly the same, with the same freeze. So though it sounds like the change in dialog focus that you are seeing might well be related to my more severe problem, I haven't a clue why we are seeing different behavior. Very puzzling. -David On May 29, 2017, at 1:13 PM, Anders Ekberg <a...@me.com<mailto:a...@me.com>> wrote: On 2017May29, at 18:45, Joel Kulesza <jkule...@gmail.com<mailto:jkule...@gmail.com>> wrote: On Mon, May 29, 2017 at 8:44 AM, David Pesetsky <pese...@mit.edu<mailto:pese...@mit.edu>> wrote: 1.

Also: if you click on the editor window while the program is in its frozen state, that window turns black. Thanks for the detailed steps. Unfortunately, I cannot reproduce with LyX 2.2.3 on OS X 10.12.5. However, there is some differing behavior I experience which might explain why you see different things. When I do NOT have a document open, I can tweak a preference, Apply, Save, and all is well. This is also the behavior I'd expect relative to my next point. When I do have a document open, I can tweak a preference, Apply, *the dialog window goes to the background*, I retrieve the dialog, Save, and all is well. I wonder if someone can track down why the dialog focus changes depending on whether a document is open or not. Can’t track down why the dialog focus changes, but can confirm the behaviour that Apply with a document open sends the dialog window to the background (OSX 10.12.5 here too if that is any clue). /Anders
