CKEditor turns "quotes" into "

I'm using a basic Wordpress tempate with a wysiwyg plug in FCKEditor. I also have various plug-ins installed that allow me to use a shortcode with quotes. The problem is that FCKEditor automatically turns quotes into "

The work around I have been using is submitting the changes on the page in html source code mode rather than design view. Any fixes?

For example:

[twitter_stream favorites="justinbieber" count=3 include_rts="true" new_window="true"]

turns into

[twitter_stream favorites="mycellphonedied" count=3 include_rts="true" new_window="true"]
