Freeze when WAIT line is asserted and Step to next instruction is clicked #22

When the WAIT line is asserted and the "Step to next instruction" button is clicked, the whole application freezes.

Ouch yeah, that's because I do something really stupid here which ends up as an infinite loop if the CPU doesn't make progress:

Thanks for catching that, it will be a while until I get around fixing the issue though, I'm currently deep in other things.
