Assuming you are running bash: is is bash option 'checkwinsize' set?
You can check by running 'shopt -p | checkwin':

[cerdea-aws]cerdea at xango3:/build/buildd/qa-kernel-sru-tests$ shopt -p | grep checkwin
shopt -s checkwinsize
[cerdea-aws]cerdea at xango3:/build/buildd/qa-kernel-sru-tests$

if it is not (the output above states mine is set), then you might see
this behaviour.
