VS/SQL Mgmt Studio question - how to stop VS from opening a new SMS for each .sql file

Question

In my Visual Studio project I have a folder containing a number of .sql files. I have set VS to open these files with SQL Management Studio by default. The problem is that a new instance of SMS is started each time a .sql file is opened. This is really annoying when doing a project-wide Find in VS, when VS opens every single .sql file - right now I have 109 instances of SMS open!!

On another PC I don't have this problem - if SMS is already open, each new file is opened in the existing instance.

I can't see a setting in VS to control this .... how do I stop it?
