I am having an issue with dual screens when i go from one to another and use my mouse, my project song has dropouts
from clicking from screen to screen if i stay on one screen its okay & that’s not okay! anyone know what the hell this is about? 
I think you may get some useful responses if you change the title to something like “Dual Monitor issue” and list some of your computer and software info in your forum signature. Hard to make an evaluation without that info.
