archive block not align properly

Hi, I had used archive module in my site. It is a good module, but i have noticed some issues. If block cache is enabled in the site, then the archive block's layout will be changed for anonymous users, but for logged in users it works fine. The exact problem is that, archive calendar will not be aligned properly with the sidebar. It is because, archive.css is not loaded when you are not logged in. The block contents are cached but the css and tableheader.js files are not cached. The module works fine if the block cache is disabled or if css is copied into the active theme's style.css.
