Question: MathMLViewer

I am creating a maplet application which requires to provide theorems, definitions, and formulas with mathematical symbols. I used MathMLViewer element but it was very unfriendly. Is there any way to control this element to make the statement readable? For example: mu=sqrt(u[1]^2+u[2]^2+u[3]^2); angA:=arcos(u[1]/mu);angB:=arcos(u[2]/mu);angC:=arcos(u[3]/mu); t1:=`Magnitude of vector u is`*mu*`Direction angles are:`*`A=`*angA*`, B=`*angB*`, C=`*angC; with(Maplets:-Elements): maplet:=Maplet([[Mathviewer('fonsize'=10,wrapped=true,width=300,height=180,value=MathML-Export(t1))], [Button("OK",Shutdown())]]):Maplets-Display(maplet); Although this typein code works, the layout is ugly. I want one line for mu, one line for angA, one line for angB, and one line for angC. No matter what I do I can not let MathMLViewer to layout the way I wanted to. Help any one! Thanks in advanced.
