Hi everybody,

I figured out that it is not because the fields are not treated nor they are
overlapped by other materials. Only the JavaScript failed to excute the "
Toggle_Hide" function. When I deleted hidden from
\setupfield
[HelpSetup]
[width=1.2em,height=fit,frame=off,option={readonly,hidden}]
the fields are shown and fail to hide now. I think it can be a bug.

I'm still looking for a solution but I'm new to ConTeXt. I hope you can help
me with it. Any suggestion will be OK.
