Applications do not close with new kernel

[Roger]

Thanks but the mouse is not functional when this happens.
problem with the gnome3 desktop is the lack of easily findable shortcuts
and hot keys.
I cannot find a hot key to bring up a terminal so cannot try ps aux and
kill the app that way.
The only option is to switch to another login, I've tried everything I
can think of.

Yep! I thought of that but if we ignore problems by disappearing them by 
using other apps then the problems continue.
For me personally, highlighting an issue may go some way toward a 
resolution.
Gnome 3 has  significant issues to be resolved, many of which have been 
previously discussed.
Some dev somewhere will become aware of it and make a fix.
