When I open my link on 2 machines at the same time it's not working.
That's very strange, that should definitely be possible. Could you please be more specific? Like what exactly goes wrong?
Very interesting system! Nice work giving the user the option of adjusting mining speed. Cheers!
Thank you for the feedback and happy crunching

I open my link on one PC and it's working, then I open it on another PC at the same time and it's frozen at 0 hashes, I tried multiple times yesterday.
