visAD examples

Hi,

In the VisAD example source codes, Test63 and Test64
on remote slave displays, why is it that when the
server window is hidden the client window stops
functioning (No image is displayed if server window is
hidden before the client has loaded or the client
display stops responding if server window is hidden)?
This happened in both a Windows and a Linux Kde
environment.

Is there a remedy to this?

Thanks in advance.

Keith
