Same here Stephen. I just solved a puzzle and wondered why the grid wasn't displayed prior to loading -- I've found it rather helpful because I create a table in Word to track my answers. However, I can see how displaying a grid beforehand can make cheating possible.
My times have gone down considerably now that I've been playing more often. I've even had some under 3 minutes. But under 20 seconds is just too astounding to be believed. You can't even read all the clues and fill in the grid that quickly.
I'd like to add my thanks to all the others -- you do a great job.
