I just noticed that the LaTex images in some library entries are not displaying properly. Instead of displaying the equation, you see this text: Click to see the LaTeX code for this image The fix for this is easy, any Mentor or Science Advisor can edit the entry and then save it (without making any changes). This appears to restore the LaTex for some reason. If you notice any library entry where this is an issue, please report it (just click where it says "Report item") so that somebody can fix it up. FWIW, I have Firefox 3.6.10 and Windows XP. Not sure if this is a browser or OS dependent bug.
