Preview opens several instances, why?

[bigfatipod]

I did some basic google'ing and didn't find this...so help is appreciated.

I am running 10.9. When I highlight a group of photos and open them with Cmd-O, sometimes Preview.app opens them in multiple instances or "groups" of Preview.app

I haven't been able to determine what causes this, how to prevent it, or what determines which images are grouped in one instance of preview versus another.

Thanks for your time!

It was tucked in the obvious Preview preferences...

Any idea how it determines "groups"? all the files I am attempting to open have similar creation times.

I've been having this too. I'll try it several times, but it'll open in a group eventually. I've also had a bunch of times where Preview won't open anything at all until I restart my computer.

this happens to me regularly as well, but usually, a second "open all" will open them in a single window...
