I have been a Slingbox user for years. I have sold probably 20 of these units for Sling. I have the Slingbox 500 now which has been working great. Then I was forced into the latest software update which not only started the annoying ads but now my mouse arrow no longer disappears! I am using this on Yosemite on my macbook air. Any idea how to get rid of the mouse arrow when I am not mousing?
