Simple tip when script set to On Load is not working.

Maybe I missed a related tip somewhere, but I'm sharing this little workaround in case helpful for others.

I understand that a script set to execute On Load may not work correctly when commands within it are accessing external expressions (green dot variables), because when the loading happens, those external expressions may not have been initiated by lemur yet when the script looks for their values. (Solution, as the manual states, is to define those external expressions within the On Load script).

I've found I'm able to get a successful behavior by using a "virtual" On Load by setting the script to Execute: On Expression   and any non zero expression.
