OK, I see the problem. It looks like your source text was copied from a web page. (Fonts Arial and Verdana are a clue.) There is something peculiar in your text formatting. I'll bet that the web page embedded that text in a table and the conversion from web to RTF has left some table artifacts in the formatting. The NSParagraphStyle settings in your RTF document look like this: NSParagraphStyle = "Alignment 4, LineSpacing 0, ParagraphSpacing 0, ParagraphSpacingBefore 0, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 16/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (\n), DefaultTabInterval 36, Blocks (\n \"<NSTextTableBlock: 0x14aa840>\"\n), Lists (null), BaseWritingDirection 0, HyphenationFactor 0, TighteningFactor 0.05, HeaderLevel 0"; Notice the NSTextTableBlock object. It should not be there. Also, the minimum line height setting of 16 points is a relic of web layout that is not particularly useful in traditional text layout (IMHO), although is not a problem per se. I ran the RTF doc through TextMate to remove all the formatting, pasted it in TextEdit, added back the formatting by hand, and the problem was gone. You could do this in code; just set NSParagraphStyle textBlocks to nil. Maybe while you're at it, set minimumLineHeight to 0 and, if you want more spacing, set lineHeightMultiple to 1.1 or thereabouts.
