[K12OSN] troubles with openoffice over 8 clients

[Sylvain Phelippeaux - Wanadoo -]

Hi,

my server : Athlon XP 2400 + RAM 1024 + Nforce2 + 2 LAN card (realtek et 
linksys)
my clients (8) : Dell P166 with RAM 64, integrated LAN + integrated video
my LAN : Switch 100 mbs + all certified cables

But : my clients can't use properly Openoffice because, when they try to 
use the horizontal bar, it's really slow...

What is the solution ?

- Do I change the video cards (server+clients) and put the same for both ?
- more RAM (on server ? on clients ?...)
- else...?

I appreciate your help...
