[Denemo-devel] New problems: no playback, nonresponsive windows

[Rodney M. Bates]

With recent versions of denemo, including the .deb files and a local build on
my system of a .tar.gz, I am now seeing two new problems.  Neither occurred
with the old version that my distribution (mint 18) has in its package repos.

1) Playback now doesn't play anything.  The cursor in the display window 
advances
   through two whole rests and to the third note, then stops.  No sound is 
heard.

2) After attempting playback, some windows sometimes will not come to the top,
   won't take the focus, and won't respond to some other mouse events.  This
   includes windows not displayed by denemo, e.g., command line windows, and
   clicks in window borders, which presumably should be handled by the window
   manager.  Killing denemo gets things working better, but not entirely, e.g.,
   this email composing window will not come on top of my media player window,
   although I can drag it sideways out from under.

When I start denemo at the command line, I see this:

BTW, My locally build denemo passes its test suite.
