===== What do I need to do to be able to run with ("enable") overlays? =====

The server needs to be configured to run with overlays by editing the jacs.ini file:
^In section labeled:^'[Node Definition]'^'[Simulations]'^
|Add line:	|Comment=Overlays Enabled	|OverlaysAllowed=true|
|Comments:	|(Optional) where "*" is 1, 2, 3 or 4, incremented from the number of comments which already exist; these comments appear in the comment fields in the JACS Monitor tool	|This section will need to be added|

This is required for __running__ a simulation with overlays.  

Located on the server, this entry in the file enables users on the JACS to execute simulations with Method Overlays stored in the General Data component.  If set to "false", the simulation will disregard the method overlays and execute against the baseline code (image).  


If set to "true", the method overlays will be compiled at runtime during initialization.  Those successfully compiled will replace the existing methods for the duration of the simulation.  Those which did not compile for whatever reason will simply be disregarded, and their failure to be applied will be instrumented in Debug Overlays. 

__You must restart the JACS service after making changes to the jacs.ini file.__
