Circuit doesn't quite work as a subcircuit.

So I'm making a voltage comparator.  When the inverted/reference voltage is higher than the non-inverted it outputs a few millivolts.  If the non-inverted is higher then it outputs a voltage just a few millivolts under the Vcc.

I connected a fixed volt component for the Vcc, one for the inverted input and one for the non-inverted input.  To manually test the comparator getting fluctuating voltage I clicked the non-inverted voltage source on and off for a while. It works perfectly every time.

When I made the comparator a sub-circuit and try this it works a few times, then gets stuck on some value under 1V.

Hi.
I think this issue should be solved in last version 0.4.15 stable:

I guess I should have said that I'm using 4.15-SR7.  Unless you put out another minor revision since it first came out.

No.. that is the last.
I did a quick test and it looks to be working for me.
But when I finish what I'm doing I will have a closer look.

It dawned on me that a much better test of flickering voltage was to attach a clock to the non-inverted output.  That seems to work just fine, so I'm not going to worry about it.

Just to completely close this out, I was still having problems till I realized that the two vertical 10k resistors didn't belong. I deleted them and now the circuit is completely stable.
