Hello, the previous problem is gone, now large amount of text can be transfered. Really great.
A small qirk is left, if i copy a graphic in Windows and try to paste it X11 OpenOffice it get the message that the desired format isn't available in the clipboard (no surprise here).
But after that the Windows clipboard is blocked (no copy, no paste, only error messages) until i put something in the X11 clipboard. Maybe this the same problem you didn't want to be mentioned until someone found a solution.
Bye Holger
