MAKE_ICON( ) question

Let's say that you are going to create a light.By the book appears to be:MAKE_ICON( ) // ON StateMAKE_ICON( ) // OFF StateMAKE_STATIC( ) // Backgroundhowever, it seems that if your gauge is going to be placed onto the background of the larger panel you could do this:MAKE_ICON( ) // ON StateMAKE_STATIC( ) // OFF Stateand be just fine. In fact, I have tested this and all seems to work.What are the disadvantages to doing it this way, if any that you may have experienced?Patrick
