Fo those of you using Consolas...
Microsoft's version of Consolas displays on the Mac and in TextMate with an incorrect line-height, most clearly exhibited in selected text, highlighted lines, and spelling error underlines. This makes writing in Consolas irritating to me.
The version of Consolas that ships with BBEdit has a correct line height but no italic or bold variations, which also irritates me.
If you extract BBEdit's Consolas from its package contents, install it and disable Microsoft's "regular" weight, Leopard seems to use the correct line-height information from BBEdit's version and apply it to Microsoft's italic and bold weights.
Now Consolas is beautiful.
