Problem with NumericStepper and MovieClip's gotoAndStop

[tks423]

I have a NumericStepper that increment/decrements the slides in a MovieClip called libMC:

<mx:NumericStepper id="slide"
change="{libMC.gotoAndStop(slide.value)}" value="1" minimum="1"
maximum="{numberOfPages}" stepSize="1" />

For some reason when I am on the last slide and try to go back to the
second to last slide (either using the down arrow or entering the
second to last page number in the textbox and hitting Enter on the
keyboard), I still remain on the last slide. This problem ONLY occurs
when going from the last slide back to the second to last slide. All
other slide transitions work fine.

Any ideas?
