Hi, I'm running Mathematica 6 on OsX (10.4) and have been experiencing difficulties generating a table of random numbers (a table of random matrices actually). 
matrix = Table[RandomChoice[{-1, 1}, {4, 4}], {250}]
for a table size less than 250 it seems to work fine but for larger sizes mathematica is flattening out the lists:
matrix[[i]] = {-1,1,1,-1}
and not
            = {{-1,1},{1,-1}}
As far as I can tell this is only happening with the RandomChoice command (RandomInteger and RandomReal work fine). Does anyone know what is happening? is this a bug?
thanks
