"The project that you are attempting to add to source control may cause
other source control users to have difficulty opening this solution or
getting newer versions of it. To avoid this problem, add the project from a
location below the binding root of the other source controlled projects in
the solution"

Visual Studio 2005
I added a setup project to my solution and it was created in a subdirectory
at the same level as the root of the other projects in my solution. The
solution was added to sourcesafe before i created and added its projects and
everything went into sourcesafe with no problem except the setup one. When I
try to add it, I get the above error
\projects\MyApplication\setup
\projects\MyApplication\module1
\projects\MyApplication\module2
\projects\MyApplication\startupmodule

I didnt get this with visual studio 2003 and I cant see why other source
control users would have difficulty opening a project on same directory tree
node as remainder of the solution. I also prefer to keep setups within its
owning solution directory tree.
How can I solve it please? Should I have had another root directory between
\projects and \myapplication?
