Problem with mouse

[Vineesh <vi...@hc...>]

Hi all,
   Now i am running a four terminal pc with 2.6.7 kernel and redhat 9.0.
My problem is when i loading some heavy applications, (like open
office), the mouses drags. also the total system gets slow for a while
say 20-25 seconds.
I am using a p4 3.2 Ghz processor and 512 MB RAM. I tried also with i GB
ram also still the problem persists.
How ca i solve this problem?
regards
       vineesh
