[ardour-dev] latest CVS commit

[Paul Davis]

    * fix nasty bug in design of message dialogs that could
       cause GUI lockups and other nastiness whenever they
       were displayed. also involved general handling of
       all requests sent the GUI thread.

    * check for write access to the session directory before
      attempting to load.

    * make control points visible again when entering automation
      tracks

    * unset keyboard target when the target is deleted (fixes
       an unlikely but real crashing bug)

    * no more ugly, flashing mixer window when
      adding/removing/reordering strips

    * freeze playlist while adding newly captured regions

    * fix typo that caused plugin MIDI binding to attempt to use the
      MMC port, not the MIDI port

    * libgtkmmext: 6.3.2
      libardour:   0.883.1
      ardour/gtk:  0.584.0
