Question:implicitplot of procedure that calls fsolve

Hello Folks:

I'm trying to generate a plot of a procedure that uses fsolve and I get the following error message:

> implicitplot(IC(2, x, y, 1, 1), .1 .. .9, -1 .. 1, filled = true, numpoints = 10);
Error, (in fsolve) x is in the equation, and is not solved for

It seems that Maple is passing x to the procedure IC and not the numerical value of x.

I tried, without success,  to delay the evaluation as suggested here http://www.maplesoft.com/support/help/Maple/view.aspx?path=cannotdetermineifthisexpression

If I call IC with numerical values for x and y I get a numerical value.

Any ideas or work around? The code follows attached.
