If you have dvipng installed, this may be due to the fact that when a font is missing it is created on the fly by mktexpk (or alike) and its output gets mixed to that of dvipng. This output confuses the lyxpreview2bitmap.py script, which thinks the font is not available. If this theory is correct, you should simply close and then reopen your document to see the previews. -- Enrico
