I'm learning and loving RTI, but not really sure when I should be using a system macro or a stand alone in my macro.

There is that message on the System Macro editor that says "this should be used only for special situations, etc."

But I've seen many systems that have tons of system macros.

What got me started on this is I'd like to program a "Please Wait" screen and this can only be done in Stand Alone.

I just need a bit of education that's all....
