Adding an .ico Favicon

Hello

I'm trying to add an .ICO favicon so it shows up on IE/Safari, but when I try and upload the favicon to Design – Browser Icon, it says it only accepts JPEG, PNG and GIF, despite saying it accepts .ICO in the description.

Any ideas? I have a PNG favicon with a transparent background but it shows as a black cube in Safari, which I'd like to avoid.

Cheers
Graeme

Same problem here! Frustrating

Same problem here. Has anyone found a workaround? .ICO is the preferred file type for favicons from my research...
