But surely that showed have shown how automated it is. You can then look
at the setup for each example. See whats in the blue "SS" dialog run

But I think this is still a matter of opinion. I have had many newbies
who say how great and easy it is to use right off the bat.

I think that you are probably a bit "conditioned" to how EWB works.
SuperSpice really is simple, imo. I think your trying too hard.

But it does not seem to me that the issue here is with the GUI. You seem
to be having problems with the circuit itself.

Ahhmmm. That means you had AC enabled! It can only do what you tell it
to do! There is a row of blue buttons that enable/disable run types.
They have fly bys that tell you what they do!!!
For each run type enabled, a graph will be displayed. You can then tab
to each one. If you run the diffamp example, you can see exactly how

Again, how did you set it up? Did you give it a transient spec, or AC

I bet 100:1 if you seen me your name.sss file, it will have a basic
error in it.

Nope. You don't need to hold it. You just click it so that it gets
selected. To delete other components you only have to have the mouse
over them. If the mouse is locked onto a waveform, pressing delete will
remove that trace.
SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
