glmmpql and lmer keep failing

Hello,

I'm running a simulation study of a multilevel model with binary 
response using the binomial probit link. It is a random intercept and 
random slope model.  GLMMPQL and lmer fail to converge on a 
*significant* portion of the *generated* datasets, while MlWin gives 
reasonable estimates on those datasets. This is unacceptable. Does 
anyone has similar experiences?

Regards,
	Roel de Jong

Formulated more directly, are there plans for the implementation of the 
crude but more robust Marginal Quasi Likelihood estimation in for 
example LME?
