Stefan, were you able to narrow down the problem?
I have not yet added any extra debugging commands to the program, I was
thinking that ignoring invalid commands would be a simpler fix? I'm
no programmer, not sure if this is even the real problem.
If you dont mind, if you could share the extra debugging lines you've
added, i will add to mine to see if we can narrow down the problem.
