R help - Jan 2012 - Error formal argument "softmax" matched by multiple actual arguments

I am running the nnet package as 


>
neural.soft<-nnet(custcat~region+ed+marital+tenure+age+address+income,size=3,softmax=TRUE)

This returns the error message : formal argument "softmax" matched by
multiple actual arguments 


Here the dependent variable "custcat" is a factor with 4-levels. This
error
does not crop up for any other arguments of nnet(), including entropy=TRUE,
linout=TRUE and censored=TRUE

identifies the error message formal argument "< >" matched by
multiple
actual arguments as a bug arising out of the R-internals function matchArgs 

Is there a work-around to this problem? I am using R version 2.12.2
(2011-02-25)
