Switched from other pool today

All ok but... why all of my workers looks active with the same kh/s and difficulty? Only half of them works actually, of course with different speed. So can't check which of them disconnected while using the web interface

why do you need to check them.
if you have run them, they keep running untill you pc turn off.
all my workers stay not active but I know that there are 2 running.
