Hi wolf11th,
I just tested your code, it works fine for me.
Can you reproduce this issue on demo http://cutesoft.net/example/general.aspx?
If so, please shows me the steps, I will check it and get back to you as soon as possible.
Below is my steps
1. Link to http://cutesoft.net/example/general.aspx
2. Clean the content and paste the code you provided into html view
3. Back to normal view to start the spell check function
Regards,
Ken
