Re: st: problems with the -ereturn repost- command

Thanks alot, that seems to be the issue indeed.

although -glm- works fine, I'm afraid it doesn't solve my problem, I'm 
writing some 'pre'postestimation command, it does some modifications of the 
estimated b matrix and saves back to e(b) for any postestimation commands to 
follow afterwards. So it might mean that it won't work with -probit- 
and -logit- this way...
