VS launches in new window / instance

[CouponPages]

I have been having trouble with a new installation of Visual Studio in that whenever I click on multiple ASP files from Explorer, it launches another instance in a new window, rather than just opening it in the existing window.

I noticed that if I use the right mouse and select "Edit" rather than "Open" it works correctly, but it's much easier to just double click.

Any idea how to change it to edit in the same instance by default?

This is not helpful, since I have seen what you are talking about, and I do not know how to change it, but...

Why are you opening ASP files in Explorer at all? The IDE is set up so that you are doing everything within a project. You should only be opening ASP files from the project explorer in VS, adding files to the project if you need to edit them.

Most of the time, I'm searching for files in multiple projects and directories for keywords or variable name. My search program uses an Explorer output interface.

With VS6, if the search would result in a dozen files, scattered among a handful of directories, I could open all of them one by one and each file would open in the same instance.

I realize there are search features inside of VS.NET, but my utilities are a bit more sophisticated and it just bugs me that the older versions of VS worked fine and the new version doesn't. I don't see any reason for a new instance of ever open when clicking on a file.

I assume there is a way to chance the default behavior of a double click in Explorer to Edit rather than Open (which launches the additional instances), but I still can't find it.
