Player Lock a one way street?

[Cory]

I understand the basic principle of this command but how do I lock the other way? IE where’s the command that prohibits the macro from running if another macro is running?

Wait for All Running Macros to Complete before Continuing

With this option selected, the macro does not start until all other running macros have completed.

Obviously this option could be used but this delays execution, not prevent it. It seems to me that to be truly effective we need to be able to control it in both ways.
