VS.NET 2003 won't allow check in new webform into ASP.NET web root

[Terry]

Hi All,

I'm having trouble checking in new webform or any type of file into ASP.NET web project's root directory.

After I added new file into local SourceSafe controlled project, everytime I tried to check in new files, the error message box pops up saying "None of the items in the selection are valid for this operation".
And then if you try to check in at the project level, the check in dialog box displays only web project file only not the actual new file.
As a result I can't check in new file in the web project's root directory at all.

This is really weird because you can check in new files in other sub directories.
Only the root directory has problem checking in new file.

Any idea?

Terry
