Hi everyone! I am completely new to the Mac world. I have been a loyal Windows user for over 20 years. But I wanted to try out the Mac side of things. I have been a user of iOS for some time, though. I have been a regular reader of the MacRumors Forums for some time, and I really think you guys are so knowledgeable, and I have huge respect. Introductions aside. I have a question, and I hope that this is the right forum to put it. I use Google Chrome when I browse the web, and I usually have 2 windows open with perhaps 1-3 tabs in each window. One day I was reading a thread here on MacRumors, and I had Facebook open in another tab in another window. Suddenly the window with Facebook page came up. And I am not sure why. The MacRumors page I was currently browsing was a full screen window, and then suddenly Facebook was there in a non-full screen window. Is this normal? Is it a sort of notification? I have done my best to replicate this, but it seems to be rather sporadic. It also happened once with Twitter, but it doesn´t happen with every notification in another tab in another window. This might sound paranoid, but does this mean that I am hacked? Sorry for stupid questions, but as I said, I am completely new to the Mac world. Oh, and all programmes are updated. I will truly appreciate any insight into this. Cheers!
