EVALUATION Commit to fix in Merlin (SQE yellow bug). eric.hawkes@eng 2000-05-07 Name: biR10147 Date: 09/01/2000 ###@###.### The only way to deliver mouse events to the components when the mouse is outside the window is to capture the mouse on each pressing. AwtComponent defines standard behavior, and AwtLabel inherits it. ======================================================================
