I think his question refers to the abnormal font changes which occur while editing OL web sites. People seem to be using this forum for Office Live suggestions, but it was meant for OL Community suggestions. There is actually a suggestion forum for OLSB under "Others."
Word has it that there has been another attempt to fix the OL font problem. It may apply only to new pages created since the fix, so time will tell. In the meantime, the best way to prevent the problem from occurring is to avoid a lot of re-editing of content in situ. You can change the text, but don't change any attribute (color, size, bold, underline etc.). If you need to change the formatting, copy the text from 'View' mode, paste it on a test page, reformat it there, then copy the whole thing back to the final location. At least this seems to be working for me. If I get a chance, I may play around with a new page to see if the latest fix has taken hold.
