AutoSketch 10 Windows 7 Opening new files open in same application

[cisco2013]

Initially, opening up a new file after AutoSketch was already open initialized a new application opening up within Windows 7.  This was great!  However, something recently changed.  Now, when I open up a new file, it is opening up within the same application.  I tried changing a few things in the registry but it looks like when I reopen AutoSketch it overrides any changes I have made in the registry.  Anyone know what would cause this or would cause AutoSketch to change the way it is opening files?

Try a Windows System Restore back to a week or month it all worked and see if that helps.

I'd love to know how you did it. A bunch of us (from several months ago) are frustrated at having multiple 'Sketch sessions running!
