I cannot seem to find an input slider in a Working Model file. Where is it?
The slider is probably “off” your computer screen because of your computer video resolution. As mentioned earlier, the Working Model files were designed for a resolution of 800 x 600. If you choose a lower resolution for your monitor, it is possible that the sliders are off the screen. To “retrieve” the sliders, set your monitor to a higher resolution (800 x 600 or above).
