Weird circuit behavior at breadboard
when the NPN is turned on the PNP turns on 
when the PNP turns on it feeds 1.5mA current to the NPN base.

To turn the NPN off you'll need to remove enough of that 1.5mA to get the base voltage below 0.6v 

With that 11K there you're going to need -15V or more to manage that.
