equation trecker questions.

I was playing with the equation treker that came with GUIKit release.

When it was first released, I didn' see much use for it, but now I
have some needs for it at the moment. Well, I coudl live without it,
but it will help me a lot.

So the questions are...

1. does equation trekker work with algegraic expression like
polynomials? Because the following doesn't work.

In[9]:=
{d= 0.1, c= 1, n= 5};

EquationTrekker[(b c y-a y^n +c y^6)/(b+y^5), {a, y}, None, PlotRange-
>{{-10, 10},{-10, 10}}, TrekParameters->{b-> {10, {0,20}},a -> {20,
{1,100}}}]

>From In[9]:= EquationTrekker::ncsol: Could not compute the solution
sol

Out[10]= $Failed

What do I need to change u there in order to make it work?

2. Does v. 6 have equation trekker and has it changed much at all?

Thanks for any info in advance.
