Why does my min:sec timer decrement while not enabled?

Question

My application uses many minute:second timers that must be displayed to the operator as mm:ss.
The attached simple vi does what I need except that the count-down-time value stored in the shift register decrements even when the timer is not enabled.  There may be a blindingly ovbious logic error that I can't see, or there may be something subtle in the way LabVIEW operates that is tripping me up.
In any case, the shaft register variable (Hi-1) begins decrementing as soon as you run the vi.  It should not.  It should hold the value set by the control called Timer until the Start button is pressed.  It should stop decrementing and revert to the Timer control value when Abort is pressed.
Can anybody see my error?

tbd, here you go:
BUT when i rebuilded the vi, i did not see the same issue, but when i recompiled the Vi the issue remained, and when i converted the timed loop into a normal and back the issue was gone as well. So I think there something with this VI, have you done the 8.0.1 update?
Was there anything done special when making this VI?
