Really interesting!

I tried:

Step by step:

1. open terminal enter emacs -Q (expect emacs to launch), emacs launches
2. enter Emacs buffer, blinking cursor shows, enter text using keyboard (expect text to show on buffer and use emacs commands), text shows in terminal
3. open chrome, try to open buffer expect to be able to open emacs buffer ->can't switch to emacs buffer
4. minimize chrome then select emacs buffer window expect to be able to select buffer, cursor to blink and be able to type in buffer -> no type comes out, error audible occurs and no text in terminal.
5. Switch to terminal FIRST, then buffer loops back to step 2

It helped identify something weird in that it seems that when I try to switch from a different application back to the buffer I can't. I have to go to terminal first then to the buffer. It's telling me that the terminal window is activating and not the buffer window.

Not sure how to get it to activate!
