Karen, I've having issues with the text editor and not just on this site. On the quick reply in the visitor message, the quoted reply appeared scrambled somewhat until I doubble clicked on it. I have a similar issue on Facebook.

This new computer is using IE 9.0.8xxx. I think I will download Firefox first and then google chrome to see if there is an improvement.

but I was wondering if there is an add-on to help. I did have to load JAVA to get some stuff working.

And keyboard shortcuts don't work in the editor. hmmmm I may have some settings to check out.
