sparseM and kronecker product_R latest version

Dear all,

I just installed the new version of R, 2.10.1, and I am currently
using the package sparseM. (I also use a 64 bit windows version)

I got a problem that I never had: when I try to multiply with a
kronecker product (%x%) two sparse matrixes I get the following
message:

Error in dim(x) <- length(x) : invalid first argument

I never had this problem with previous versions of R.

May you help me?

thanks
