Trying to create new PO. Two different people on three different machines see the same problem. Two different XP machines, and on the server itself. Right click on Domain > New > Post Office. "Create GroupWise Post Office" window appears. Fill in Post Office name, container, DB Location (local whether on Linux or XP). Make platform Linux. Click OK. Link Configuration Wizard choose TCP/IP link. Click Next. Enter IP address. Click FInish, and you are immediately taken back to the "Create GroupWise Post Office" window where the cursor is blinking in the "Post office name:" field.
Like I said, I tried this on the server itself, on my Windows machine, and had someone else try and do it on another PC, all with the exact same results.
