Cannot run spark. Spark process still running

Sometimes I can´t run spark 2.0.1… When this happens, I go to the Task Administrator and there I can see spark process running. After killing this process, I can run spark without problems, but I don´t know why spark hangs sometimes like this…

Another abnormal behavior is that when you run spark inmediatly after rebooting Wildfire server, spark starts but you can´t see menus. I think the problem here is that you need to wait Wirldfire Server to start, but spark should do that for you, and not trying to start and getting in that rare state…

Thanks in advance,

I think the first problem, is not a problem, because really spark is minimized, not closed. I did not realize that pressing “X” button what you really do is minimize, not close spark…

The second problem still happens… twice today… and not necessary if you start spark when Wildfire is starting…

I have this problem too. Even after i kill the process it does not start too. I have also tried restarting my machine. It does not helps also.
