Yes. A couple of warnings, but this TypeError is thrown in the console and looks related:
Uncaught TypeError: Cannot read property 'popover' of undefined

> Are you seeing the issue occur on the same dialog?
Yes. Basically the problem seems to affect ALL Touch UI dialogs at once and then fixing it for one dialog--any dialog--then fixes it for all dialogs.
Also: it does seem like this might be deployment-related--although we haven't quite got that proven yet--but again, we don't have to change any code/config to fix it--just open the cq:editConfig and re-save.
