Resolution:
Launch BW process : X connection to localhost:20.0 broken (explicit kill or server shutdown).

The client application gets this error when connecting to Xserver (say Xwin32 on Windows)

In most cases, unsetting the  the DISPLAY environment variable helps overcome the above exception.

Some other possible reasons for the XConnecton error to the Xserver could be:-

* Not starting XWin32 every time one connects to remote access.
* Incorrectly configuring XWin32 or your SSH Client. (X11 forwarding)
* Changing the $DISPLAY variable from the default. Let the SSH Client set it.
* Running an incorrectly configured personal firewall that stops traffic on the localhost.
