+      * Fixed: When wave files were edited allocation was on stack which caused crashes for larger selections, now done on heap (rj)
 10.07.2010
       * Added: Insert measure, inserts empty space and moves everything after playpointer to the right and
                Part-insert, pastes parts and moves everything after the paste point to the right
