keyboard stutters

since installing Xandros 4.0 home premium over a year ago, I have been putting up with a stuttering keyboard. Basically what is happening is when typing, letters need to catch up which is fustrating at times. Its very similar when having resource problems in windows.

I have been using a wireless keyboard and thought that might have been the problems but when the same thing happens on a wired keyboard.

Any suggestions would be appreciated.

Thanks

Have you checked to see that there are no incorrect settings in the Control Center settings for trhe keyboard?

as far as I can tell, the settings are good. I compared it with another computer that does not have this problem.
