I uploaded my Pfennig font to the new OFL site just to test the interface out, and I noticed that the PNG-preview for the Bold Italic did not pick up any of the glyphs: http://openfontlibrary.fontly.org/files/Daniel_J/72 Re-uploading the .otf file did not change this. I've verified in FontForge that the .otf is not corrupt.
Also, in IE the four weight/style combinations show up correctly under "Font Linking with @font-face", but in Firefox 3.5.2 Medium Upright shows up for all four. Best regards, Daniel
