With some products, when I click on the icon to switch between WYSIWYG and the HTML display of the product description, it doesn't do anything.

Also, it won't save any changes you make to the description text in WYSIWYG mode. You can change the WYSIWYG text but when you save it through the Preview step it reverts back to the original text.

The only way I can change the description on those items is to cut the text, put it in an editor, then paste it back into the box as HTML.

This is not happening with every item, just some. No clue what is going on.
