after 7MTT-migration of a CIFS-vFiler fsxxx from 7-Mode (8.1.4P7) to cdot (8.3.1P1), there are problems with file access.
The problem occurs in the "MAPInfo" application (GIS Mapping - by pitney bowes).
Within a lot of program modules are using an internal "FileExists()" command to check, whether the user is allowed to access a specific file in a specific directory.
After migration this "FileExists()" command always returns "True", if the file exists in the corresponding directory; even there are no ("windows"-)permission to access this directory!
I am well aware that no problems from external applications can be resolved here. But what are the changes from 7-mode (8.1.4P7) to cdot (8.3.1P1) that could cause such a phenomenon? Has anyone ever had similar experiences?
