Indeed. I have (had) bought PSpice 3 times and also started on the dos
pspice, prior to its integrated text editor. Ahmm... I certainly would
not admit to having a broken copy of dos pspice, in the event that I
ever did have such a copy:-)

It has been *much* improved over the last two years. See the latest
Graph windows were certainly not automated enough. Now its a no brainer.

But the alternative from other vendors is waiting months and months to
get needed bug fixes. If its a main one that gets reported, I try and
post a fix within a day. Help files are much improved.
Ok, I still update *quite* a lot. Even yesterday I added a neat new
feature. You can now use the docked file browser to place circuit
sections just as you would a single component.

I could make some more generator symbols with single set-ups in them. I
don't set-up the DC/AC source with a default AC value because this would
default inject signals into the power lines as well.

I suppose though that I am not really targeting newbies in
*electronics*, but rather the newbies and experienced users in *spice*
itself. SuperSpice is *not* designed as a *teaching* tool for
electronics. Its designed for someone who already really knows the
*basics* of *electronics*, but may or may not be that familiar with
simulation. If you understand the basics of electronics then SS should
be simple to use.
SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
