Re: [Tauruslib-users] Taurus 4 preview available

[Teresa N. <mar...@de...>]

Hi Carlos,
                 thanks. Yes, I also thought that it should work ...
I get the warning as you say, but after the warning the program
  crashes complaining about the model. I will have a look at the
  examples you say and fill a ticket if I think that it is a bug in Taurus.

                         Regards,
                                          Teresa
