Foliopress WYSIWYG and 404 errors (because of .html redirecting)

I am working on a site that has a few lines in the htaccess file to redirect incoming traffic with .html in the URL to the appropriate non .html page in wordpress. Having that in the htaccess file apparently causes this plugin to break because the plugin references fckeditor.html in the editor 🙂

I just changed the file name fckeditor.html to fckeditor.php and updated a few references to the .html to .php… but if/when this plugin ever has an update, my changes will be gone.

Is there a better way to handle this? From what I’m seeing, trying to get .htaccess to selectively ignore “fckeditor.html” in it’s redirect isn’t an easy task…?
