I just upgraded to LD 1.0.1.9.0.66
-I start LD.
-I begin new Project
-I give the Project a name of "Test" and leave everything default.
-I make the job single room.
-I Insert 1 Zone.
-I right click on Channels and select <duplicate channels>
-I leave everything default, and click <ok>
I get a crash and burn:
Error Assert: 'oFixture' is FALSE at line 693 in file .\appengine\project_edit\fixture_tasks.cpp (Feb 6 2009)
