The configuration is in C:\users\ken\documents\My SlickEdit Core Config\4.3.0 and the actual program is in c:\eclipse so no shares involved there. The workspace however is on a shared drive. I have the exact same version of SlickEdit Core running on a Vista 32-bit machine. I have also tried it on a Windows 8.1 64-bit machine and I had the same problem there.
