Thank you very much Brian. I hope you find time to get this fixed at some point. It will be most useful and appreciated.

Murat,
The short answer is that -bssize- just is not up to handling multple-equation estimation commands as it is now written. When you use -bootstrap- with a multiple-equation command, the names of the variables in the results dataset begin with an equation name, and -bssize refine- is not set up to deal with variables named like that. I will see if I can get this fixed at some point.
