Where do I change the optimistic concurrency setting to NEVER in SSMS?

Reason for Question:

This weekend I updated to Visual Studio 2013.  I get into my SSMS 2012 and create a simple table for a simple application.  I get the optimistic concurrency control error as I play with data in the table.  Arrrrr.  I read about it and I set a primary key on the table and now I can edit/save etc.  but I get the error message each and every time.  I do some research and people say, turn it off.  Where?  

FYI - This is NOT happening to any previously built tables in SSMS.  Only my new ones after loading VS2013.

Thanks!

That's not an error message.  What is the actual error message?

Data has changed since the Results pane was last retrieved.  Do you want to save your changes now?  (Optimistic Concurrency Control Error)

Click Yes to commit your changes to database anyway.
Click No to discard your changes and retrieve the current data for this row.
Click Cancel to continue editing.

I click Yes.  Things work fine but it's time consuming.

If I highlight several rows and click Delete - it won't let me, so I delete each row individually, clicking the Yes from the above message.

There's no way around that.  SQL won't try to keep locks when you are "live editing" the table, because you could keep those locks for minutes, hours or days even.  

Instead, to keep from locking virtually everyone else out of the table for the entire time, when you go to save your mods, SQL checks to see if the related row(s) have changed during that time.

You really should learn to use DELETE, INSERT and UPDATE statements to make changes to data.

Exactly, you CAN'T.

I'll repeat the answer more clearly:

This CANNOT be done.

Or, as I put it before:
"
