Hey guys, I have been having trouble with various push button latch circuits. even the 555 timer posted in the forums didn't work with me. In any case I found this circuit on a blog that addresses some of the problems with the talkingelectronics circuit -
(seen here)
So here is the address of the circuit I am trying and its schematic-

The issue I am having with the breadboarded circuit is that when the push button is pressed and released the LED will just flash once instead of latching on. If I take the emitter lead from q1 away from ground the LED will stay on (dont think its relevent but just including more information). I have gone over the circuit looking for misplaced wires or missing points but everything looks good to me. I can supply a picture of my built circuit if wanted (though I dont use cut to length wires so it looks messy).
Please help, this is the last component I need to finish my project which I will be glad to show off when it is done.
