Slider thumbPosition crazy values

[Dennis Brown]

Thanks Eric,

Setting the Value Format for the slider let me see that the slider does 
not increase in unit values of the scale marker even though the scroll 
distance on bar click is set to 1.  I guess the units were close 
because of the sizing I applied to the object so that it appeared that 
it was advancing by 1.  In the Variable watcher it said the value of SQ 
was 3, but if SQ=3 statement would evaluate false --I got real 
confused.  Got to watch out for that property with scrollbars.
