My site supports four language: English, Spanish, French, and Russian. When I am in the non-English language version of the site, I am unable to type any letters in the comment form. I am only able to type in letters when the first character is a special character, number or whitespace. I was able to "fix" this problem by disabling the rich text editor. Disabling the rich text editor allowed the comment form to work properly. This, however, is not a long-term solution for our site as we need that text editor. Any ideas on how to fix this?

Thanks in advance!
