Hi Joshua, thanks for the reply

I eventually traced it down to a component with a stray new line in the
value property. I fixed this and it now works fine.

Thanks for your help

I can delete a small section of my schematic and it goes away (generally ar=

I have attached my schematic in case it helps, it uses a few custom symbols=

Is there a way for me to track down what part is causing the problem... nev=
