Hello again!
Yes, that's the conclusion that I have come to also.
I have added a new graph and everything appears to be stable. I will leave it running overnight tonight and see if it has stayed stable wen i get into work in the morning!
I'll also have a thing about my code and if there is a way to tidy it up so i don't have so many nested structures!
Thanks for your input, it's appreciated.
cheers,
Iain
