Ok, I'll wait these bug doesn't disturb me anymore.  ^_^

All right, in this case I choose to note it because it appears before a
list of differents outputs. Only a comment, these "open circuit"
disappears when you choose a minor voltage on VE, for example a -2.5,2.5
or 0,2 V values.

Well, I'm "happy" to listen this, I'm going mad with this  :-|

Yes, I try it with sucess.

I'm not finish to understand this, I need to check something in my
system and circuit?

I think that you explained me the bug but language should go me to fall
in a error.

Anyway, circuit outputs are correct for now, including waveform of base
intensity that before was "too ideally" without any distortion.

Thanks too much Al for your quickly answers.
