Spell checking issue when switching between Plain text and HTML editing

The "Check spelling" GoogieSpell works fine with Plain text editing, but when switching to HTML editing should the "Check spelling" not be removed, so that it is the "spell checking" in TinyMCE the user will use?

If I use the "Check spelling" GoogieSpell in HTML editing it corrupts the TinyMCE and creates two iframes, but switching back to Plain text and then back to HTML editing the error is temporarily solved (until the use of "Check spelling" GoogieSpell)

I have searched for a Ticked but not found a exact one.

Using SVN 611 and Firefox
