Are you using IE9? The forum software is having issues with that browser....
Also let me know if you are using the production release of IE9 or a pre-release version. Our forum vendor is prioritizing updates based on QA with the production release of IE9 now available. So far, the blank post issue with the post editor appears to be one top issues.
