"y=?x" is correct !

Perhaps it's a bug with an earlier OS version.. go to classpad.net and update it (if you haven't yet done so)

I think that it's a problem in CP300's software!
I tested it on "ClassPad Manager". But there is no deffrence between CP300 v1.24 and ClassPad Manager v1.24 .
It's correct : y^2=x^2 => y=?x
But It isn't correct : y^2=x^2 => y=?2x
I waiting for your opinion ! Please tell me it soon ...

You're right, there's a bug in the drawing of the graph...
It creates a valid expression for it ( (x-y)(x+y)=0 ), and the graph solve functions work correct as well, but the drawing is wrong :/
We'll have to add it to the bugs list.. weird stuff
