Ok, bit of a development here, when I downloaded vLSO I extracted it to a new folder on my desktop, I've been trying to run the .exe from there, just for the heck of it I made a copy of the .exe and put it on the desktop, tried Jimi08's Hornet from Oceana out to the Nimitz, It works !, I hear all the LSO calls, get graded and everything, but....(You knew one was coming) when I try to change planes to Sludges Hornet or Dino's Tomcat, I don't hear anything but the plane flying, but the little green icon is green when vLSO is running.
