sorted! looks like it had somethign to do with the line-height in the previous div (navigation at the top)…a reduction of the height of this div led to the problem.
not sure exactly what happened, but its working anyway.
well, i have now removed the <hr>s in the template files. but problem still persists. the funny thing is if i remove the float:left it will stay at the left. but with that declaration enabled, it gives me a margin like the link above shows. it does work as intended in IE7 but not firefox. seems to be a css problem, i can post the code if needed.
sorry, wasnt thinking 🙂

as you can see the grey content area is centered somehow, although i have flated it to the left. the <hr> are set to display:none;
