Hello,
It appears that when you have a php statement like:
echo "Your information has beewwn submitted.";
and you highlight "Your information has beewwn submitted." and click spell check (F7), it says spell check complete...
It does not return that "beewwn" is spelled wrong. I know that <?php ?> blocks are not checked for spelling, but I assume that it would attempt to check a selection no matter where it is in the document. I might be wrong depending on what your design intention was. Let me know.
