Problem with FCKEditor plugin

Hi. There is no error. The problem with '+' in equations is that some browsers and some editors convert '+' into spaces. I think its IE that triggered the neeed for this. We therefore need some method to identify a real '+' and hence this trick.

As you have probably researched, on the whole this isn't needed. Our latex renderer will work just as well with a '+', however if your integrating our editor into something like FCK then be sure to check how different browsers work.
