Clipboard issues

[bhasker@unixindia.com]

Hi all,

  I am seeing this issue on my debian wheezy/sid. The clipboard contents 
are disappearing when the window is closed. Can someone help me please if 
they have to faced this issue ?

 Steps:
    open any window application (even xterm )
    Mark the contents of the window (which is copying )

    a) Close this window and open another window and try to paste the 
copied text. The copied text has disappeared and last text is remembered 
and pasted!
    b) before closing the window if you try to paste the paste works fine.

thanks all
