Which shell are you using? Also, what is your prompt set to?
I get exactly that occurring with bash if my prompt includes certain variable length fields, but if I use a static prompt such as " Q> ", it goes away...

I had the above happenning back with RedHat 4.1 and kernel 2.0.29, which is as early as I go, but ONLY with the bash shell - it appears not to be a problem with tcsh which is the other shell I've used...
Best wishes from Riley.
