OS X V10.7 Lion :: Multiple Files Opening When Choosing Only One

When I open files, usually .jpg, I sometimes double-click on it just to pop it open real quick to take a look at the larger picture. I still have Preview as my default graphic file viewer and up to 10.6, when I would do this it would just open the file.  When I was done looking at it, I would quit Preview by hitting command+Q. Then a bit later if there was another file I wanted a bigger look at I'd follow the same process. I've been doing that for about 5 years.

With 10.7, following this behavior produces different results. If I open a .jpg, then close with command+Q, Lion "remembers" the last file I had open, and when I double click on a file, it opens the file that I clicked on AND any previous files that were open. This could go on and on endlessly. I tried it a few minutes ago and opened 10 files by double clicking on only one. The way that I've found to alleviate this is to first close the .jpg while in Preview, then end the program. This makes sense and everything, but if I tell Preview to close, it should assume that I'm no longer interested in the file that was previously open. I suppose all of this isn't too big a deal as it only adds one additional step to my daily behavior.  But it's going to be a hard one to break after a few years of doing something else
