New puzzle format

I've tried what FinkelFrand suggested ('about:flags' etc.), but I still cannot use the training function... so I'm hoping you will fix this bug before you implement these board changes on the real games!

(I use an old version of Chrome though: Version 21.0.1180.90)
(My software is Mac OS 1.5.8, so I cannot get a newer version of Chrome)

Sorry, but the support for Chrome 21 will be dropped. I like innovative technologies, and can't be slowed down by legacy browsers.

Hi
I have a Chromebook with up to date Chrome and am experiencing suddenly (last couple weeks) inability to move the pieces in puzzle format. Hover over a square does not shade it. Board editor works fine. Refresh seems to just reset the puzzle.
