Layer positioning

Hi guys,

I’m making submenu’s using layers but how do I prevent that the position from a layer change when the site is seen on screens with different resolutions? I gave the layers absolute positions but that doesn’t work properly! On my own computer everything seems okay (if I don’t change the resolution) but on a computer with a higher resolution and/or bigger dimensions(19") the submenu’s appear on a different place (logical). What should i do to prevent this?

Thanks a lot
