Hi Anne, hopefully the spellchecker opens up in it's own wee pop up window.
Once you have gone through the spell checking and changed anything that needs changingif you click ok on the bottom right of the pop up box it will bring you back to this editing box.
Once back here if you click preview it will show your post just above this box, once you're happy with it click Post.
The only thing I can think of at the minute is you maybe haven't click post on this screen thinking the spellcheck OK button would post it for you.
If that doesn't work, let me know and I'll dig out my BFH and duck tape and see what else I can find.
