I have a dual processor computer and I am using Maple 8 (because it is much faster than Maple 11) but I noticed that Maple 8 only maxes out one processor and doesn't use both.  I am using (unfortunately) Windows Vista.  I would appreciate any suggestions.

I also have a single 2.3 GHz processor at home with XP so I'll give that a try.


I am having problems using implicitplot.  I run this code and it worked and today I tried it again and it gives me the following:


implicitplot(0=int(erf(  (T-e*t)/sqrt(2)  )*t^2*exp(-t/2),t=0..infinity),e=0..1,T=0..10);

Error, (in plots/implicitplot) invalid input: the following extra unknowns were found in the input expression: {t}

The weird thing is that this worked before (took about 10min though) and now it isn't.  Any suggestions?
