Hi!

So, ever since I updated my Mac to Yosemite whenever I open a video file in UMplayer it opens a second icon (like this http://static.tumblr.com/tryhz8g/Oebnkc2ha/captura_de_pantalla_2015-02-25_a_las_16.11.27.png) that doesn't stop bouncing in my dock and it's REALLY annoying. I've tried uninstalling and installing again but it doesn't work. Any ideas how to fix this log?

Thanks in advance!
