Is two too many?

I'd like to raise the absolutely frustrating issue that when I turn around and turn on my second computer it signs into the app and kicks me out of what ever I'm doing on my one computer. Mid match, mid what ever it is I'm doing. 

If having two PCs signed in to a single account is just too much to handle then I submit a better way of dealing with this would be to halt the login on the new computer stating the account is already in use for several reasons. 

First if the account is compromised this will halt the proper own from logging in and the will be forced to take note of the issue.

Second, by not disturbing wrongful user this gives the correct user the opportunity to fix the issue while the other is busy.

Finally, this will not kick me out of what ever it is I'm doing just because I have two computers.
