vnc4server problems

[Jérôme]

Hi,
I use vnc4server on my x64 Ubuntu (in french) 9.04.
-If i start a permanent session , this session starts in english (All 
links ans environnement variables are in english). How can I fix That?

- I can not use the copy/paste function from my vnc session to my 
windows session, even if I check the box in the settings to allow 
clipboard transfert

-is there a way to use vnc4server to share and acces the local session?

Thanks for your help
J.
