[users] Opening .doc files on a Windows shared folder

[Freeneonia]

Hello to everyone.
I'm working with Kubuntu 7.04. And Ooo2.2.
When I access a Windows server shared folder and make double-click on a .doc
document, shows the splash screen and nothing happens.
I have read and write rights.
If I make the same with a pdf file, xpdfviewer shows it without problems.
How can I fix this problem?
Thank you.
