I'm getting the exact same problem. Accordion inside 2nd tab of 3 is freezing. Visual Studio points to this line:
j.toShow[0].style[l.prop]=(g*d[l.prop].value)+d[l.prop].unit g is NaN, l.prop is height. g is set right before this: g=(l.now-l.start)/(l.end-l.start) l.now, l.start, l.end are all 0. No answer yet. R
