Hi there,
sorry you haven’t heard from anybody for a long time.
Have you updated your blog to the latest WordPress version in the mean time?
If that hasn’t helped in fixing the issue, I would recommend deleting your cache in your browser and / or trying a different browser to check for any cache issues.
