Font spacing: LyX/Mac when compiled with Qt/Mac-4.5 and later seems not to know how wide each character is for some fonts, and so the location of the cursor on screen does not always correspond to the actual place between letters. This is not a problem for the beginnings of words, but as the cursor moves towards the end of the word, its location on screen sometimes gets further and further off. (It always seems to be that the letters are displayed narrower than LyX thinks, so that the cursor appears farther to the right than it actually is, and then there's extra space between words.) I said this is true with some fonts. Two examples here: Hoefler Text Italics and Courier. The problem with Hoefler Text Italics seems to arise from the extra swashes that font has. Thus an italic "e" will have an extra swash to the right of the letter when it is the last letter in a word, but not when it is in the middle of a word; the same is true for "w", which has a swash before the letter when it is the first letter in a word, but not otherwise. LyX seems to think an "e" or a "w" is as wide as it is with the swash, even when the swash is not displayed; hence the cursor tends to be further to the right than it should be. With Courier, I'm less sure what's going on. In ERT, when I type "\LongLaTeXCommand{}", the cursor ends up an extra space to the right. Hitting left-arrow brings it just to the right of the "}", but then typing inserts text between the braces rather than to the right of them (as the position of the cursor onscreen would indicate). Let me know if that description isn't clear. As I said before, this is not an issue with LyX compiled with Qt-4.4. (I currently have both 4.4 and 4.7beta1 installed; the font issue shows up with self-compiled Qt-4.5 and with the precompiled 4.6 (all released versions) and 4.7.) BH
