Kinda a dumb sorta question and I'm not sure what causes the behavior, but once I get a track recorded one of the first things I do is set the "input' of the track to "none"...and I "save"...

The I will reopen X2 a bit later and a track I  am done with will have on its own loaded one of my input sources to the input of that track...what causes this and how do I stop it? 

Not a big deal just irritating as heck...and its a little disturbing to me that Sonar does random things like this on its own...
