      The example circuit called simple_amplifier works fine. But change the transistor to 2N3904 and it stops working. There will be lots of warnings like this:

      Warning in ‘HB1’: Inserting 1 GOhm at HB node 26/36.

      Warning in ‘HB1’: Inserting 1 GOhm at HB node 32/36.

      Warning in ‘HB1’: Inserting 1 GOhm at HB node 32/36.

      Warning in ‘HB1’: Inserting 1 GOhm at HB node 26/36.

      To fix the problem open up the transistor model properties and change Xcjc to 1.0. Now the simulation works but the transistor model has been altered.

      Is this a bug?

        I could reproduce it.
