Excavator window is not closed, and it's keep getting new jobs even after another miner started
I'am using a latest master (downloaded 2018.04.20.).

Excavator running NeoScrypt:
```

Another miner started, but the Excavator window stays open, the new jobs keep coming:

```
Note the time passed.

And this keeps going, even after another and another miner started.

This keeps connection open? Even using GPU resource? Does this affect other miners performance?

Edit:
After Excavator gets new algo, the old one still present, and gets new jobs from that as well:

After interval finishes, starting new miner, Excavator still opened and this happens, and keeps going:

Edit2: after more algorithm start and stop with Excavator, there are many low difficulty shares:
