Minuit & large # of params (once again)

This issues has been somewhat discussed several weeks ago. I need to use 
a large number of params in Minuit (~80 or so) and, as Rene explained in 
previous postings, I use the following constructor:

      TMinuit *aMinuit = new TMinuit(95);

SEEK & SIMPLEX calls work ok, however all the Minuit functions that 
estimate parameter errors (such as MIGRAD, MINOS) dont work correctly 
for parameters 26 and higher (i.e. parabollic errors & correlations are 
correctly calculated for the first 25 parameters, but not for the rest 
of it -- somehow Minuit fixes err(p)=sqrt(2) for P>25). Is this a bug or 
I'm doing sth wrong?
