Relative Path to CSS file unrecognized

[sibinpthomas]

When the CSS header specifies an absolute path the generated HTML preview takes this CSS file into cognizance. However when the path mentioned is relative the CSS file is ignored.

This works:
CSS: c:\sample_dir\sample.css

This doesn't work:
CSS: .\sample.css
