subst not working as expected?

Jan 27, 2015 at 11:58 AM
In our use case it seems that subst functionality is not working. This is VS 2012 and VS2P4 1.87. The symptom is that VS2P4 does not recognise the source as being under source control when Visual Studio see the files from the virtual drive (A:\ in this case).

Here is subst:
A:\: => C:\p4\stardav_RSA_main\RSA\RSA_main
Here is P4CLIENT:
stardav_RSA_main
Here is the client root:
C:\p4\stardav_RSA_main
I guess the problem is that there is a bit of physical path below client root which is subsumed into the subst drive? Or is this meant to work?

Thanks,
David
