I bought an app called "Air Display" which allows me to use my iPad as a second monitor. I've noticed that while I am on my second monitor whatever is on the other monitor will minimize after about 30 seconds.
Being new to Macs I'm not sure if this is some known behavior or a side effect of the Air Display app. Is this because of how I have my mac setup? If so, is there some setting I can change to stop this from happening?
