@Joe80, FYI to people that have similar problems adding info to a wiki summary as you have had:
I have found that if you add text that includes a special character somewhere in the text, the page will not proceed past the "Processing..." stage of updating the wiki summary. Try to go back and look through the text you are adding to see if there is a special character and replace it or delete it. After doing this, I have found that there will be no problems with adding to the wiki summary.
