[R] aov problem

I am using R to make two-way ANOVA on a number of variables using

g <- aov(var ~ fact1*fact2)

where var is a matrix containing the variables.
However the outcome seem to be dependent on the order of fact1 and fact2 
(i.e. fact2*fact1) gives a slightly (factor of 1.5) different result.
Any ideas why this is?

Thanks for any help
