Okay, my bad, it was entirely my fault, no Windows to blame
. [I put the wrong (meaning: default) files in the zipfile. Meaning we weren't asking the Kindle software to use the custom fonts, so, of course it didn't work for anyone but me -_-"]
If you've installed the _FONTS_ hack from the first post before now (06/23/10 03:33 UTC), unpack the two files in the zip file attached here to the linkfonts/bin
folder on your Kindle, overwriting the two existing files. And then restart your kindle, it should work a whole lot better after that ^^.
I fixed the zipfile in the first post.
