Here is a short list of things that may fix this issue:
- Please check the response using a different browser.
- Clear the browser cache.
- Try re-publishing the workbook.
- Is IE in “compatibility mode”?

I have the same problem in IE and Chrome and using different computers. Java is enabled. I've tried re-publishing under a new name and the same one. This is only a problem for vizzes I've published in the last day or so. Thumbnails for older vizzes show up just fine.
