Issue with Visual Studio.NET 2003 and PVCS 7.5

[Lisa]

When I create a new file in a project that is under source control,
the vbproj file is not being checked out. When I check in the new
file, it is put under source control, but if another developer does a
"Get Latest Version", they will never get a copy of the new file
because there is no reference in the latest version of the vbproj file
because it was never checked out.

When the new file is checked in we get the "Some reload or shell
operations were canceled or caused errors. You should close and
reopen the solution before making further changes." message.

Any ideas on how to resolve this? It worked fine with Visual
Studio.NET 2002 and PVCS version 7.5


Thanks.
