[Rsiena-help] Possible error with multi-core estimation in rev. 119

[Ruth M. Ripley]

Dear Guido,

I have corrected RSiena on r-forge.

Please would you check the new version of RSienaTest for me (rev.120). If 
it fails please would you tell me what sort of model you are fitting. 
one-mode/bipartite/behavior variables/covariates/effects...

Regards,

Ruth
