I see that you've compiled FF3 with a new manifest telling Windows that it requires administrative privileges. From what I could tell with the previous version it ran with reduced privileges without a problem, is there a reason that you did this? I just ask because it's triggering UAC now every time it launches.
I did it that way because I'm an idiot who forgot to uncheck the administrator checkbox prior to compiling the FireFly3.exe.
I just re-uploaded the FireFly3 3.03 setup file.
