New Window Closes on own
Okay so even I recognize that this is strange but it keeps happening. Safari 9 is open, I have windows open, minimized or just up on my screen and I make a new window (command N). I type in the website address, it starts loading, then it just closes. I'm not touching the computer or anything. The first few times I thought I was going nuts because I usually typed it in, then looked away, then looked back it was just gone. I have no idea what or why it is doing this. It has been going on for awhile, I believe even before I update to 9 because I remember thinking maybe it would be fixed with the update. I am still running Yosemite. I am on a MacBook Pro I haven't noticed anything on my iMac. Any suggestions would be great. I'm sure I am forgetting something.
MacBook Pro (15-inch Mid 2012), OS X Yosemite (10.10.5)
