Explorer 6 Windows only, and bug has been removed in XP SP2.
Although Explorer Windows bug with @import are
well attested, I believe I found a new one (with a little
help from Rob Ford).
Explorer Windows 6, up until XP SP2, supports
@i url(iebug.css)
If your browser imports iebug.css this paragraph is blue.
You can also use @impor, @impo, @imp or @im.
