Server :: Set Up "Kiosk" Directory - Ubuntu Ver 10.04 Server-i386; Cannot Open Odt Docs?

I am an experienced Ubuntu Linux user, but the fact is that I need some help. I recently set up a "venerable"(Pentium 4, single-core, 2.4 GHz, 32-bit architecture) machine with Ubuntu Linux version 10.04 server-i386. My objective is to set up a "kiosk" directory on it which everyone(including guests) on my SOHO network can read from and write to.

I have designated the directory "kiosk"(no surprise there) and defined it in smb.conf. It is directly under the "home" directory, as path = /home/kiosk and set the file permissions as drwxrwxrwx or, if you prefer, like chmod 777. I have a separate machine, System Librarian running Ubuntu Linux 10.04 Desktop amd64 on the network(via Wi-Fi) and a second separate machine running Windows XP Pro, with SP3, also on the network this time via Fast EtherNet(100 Mbs).

From the Linux machine, I can read a complete file list, but I cannot "open" an RTF or an ODT doc in the kiosk directory. When I try to do so, OpenOffice.org simply "opens" a blank, untitled document. JPEG and PNG files in the kiosk directory open just fine. I cannot write to the kiosk directory from this machine, either.

From the Windows XP machine, by contrast, I can list files, open RTF and ODT docs(using Microsoft WordPad) and write file to it without any apparent problems. The file format on the server(Iguanodon) is ext4. Obviously, I have made some sort of mistake in setting this share up,
