What do you mean by "everything else" here? What cases is user cancel not
appropriate for?

[viettrungluu, 2011/01/31 19:01:41]

Conceivably, other things (not directly done by the user) might make the context
menu disappear -- e.g., some other program grabbing focus. It's not worth the
TODO though, so I'll get rid of it.
