this seems to happen from time to time. Last time it was caused by a member copy and pasting the entire page into their comments post. Perhaps something can be done to prevent this from happening....???
I'm sure you'll spot the issue as soon as you load the page, but basically the puzzle has another chess board imposed over the top of it that prevents the puzzle from working.
Sorry about that! I've deleted the comment
How about the endless NOOOOOOoooooo that takes up the whole screen of pictures so big your the second one to comment but your on page 2! It would be nice also if you could resize a picture but that isn't working anymore so its one size fits all now too.
