Involuntary recursion

Hi,
I've been working on an OS and attempting to make a web-controlled forcefield for my base so i can monitor my base on vacation and such. However, when i run the program (linked below) i get a lot of spam "field off" "kill on" "done" "updated states" which should only happen once, and no messages from anything else. If i leave it running for a bit, it eventually stops due to stack overflow. Cpuld anyone help me?

the last thing drawScreen does is call buttonActions. The last thing buttonActions does is call drawScreen. This is a Bad Idea.^tm

Thanks! (How did I not notice that :blink:/> )
