We use a team version of Xbench, it seems that xbench needs to authenticate one or more times one day. Xbench works successfully if we use a working VPN, while Xbench would fail to authenticate if VPN is blocked (Xbench asks user to provide username and password; it still fails even when we enter the right username and password). Could you please provide a workaround to this problem. And because of authentication, we always fail to call the source file by pressing the shortcut (Ctrl+E) in Xbench, which means we could not open the Polyglot source files by pressing the shortcut (Ctrl+E). Thanks in advance.
