Having an issue with a Windows 8 box. When we use a certain program with a working directory on another PC, the Windows 8 PC can't write to one of the data files that the program uses. All others seem okay. It is acting like there is a firewall or A/V blocking the file. If the program is pointed to the same file locally, it works fine. We originally were seeing an error that said something about write caching so we turned that off.
