Then I clicked in the echo area, which caused the *Messages* buffer to appear, and the last line says "Quit this Ediff session? (y or n) y". As before, mouse input is complete normal; I can activate menu items, drag the mode line for the upper window around to resize it, etc, but no keyboard input registers. In particular typing C-g a bunch of times has no effect, nor does C-x C-c after that. For completeness, in case this wasn't captured in my original bug report, I'll mention that during these experiments I'm running Emacs on Ubuntu inside of a VirtualBox instance on a Mac. There's one other Emacs-related peculiarity I notice only in this environment: whenever I start Emacs and desktop-save-mode is restoring my buffers (which takes much longer than elsewhere for a comparable number of buffers), the entire system slows to a crawl.
