I'm facing a delay with the mouse's movement when playing the puzzles.
I'm using Firefox 55.0.1 (32-bit).
I've had the same problem way back, and then it was solved by this thread - http://www.conceptispuzzles.com/forum/tm.aspx?m=36236 (setting dom.ipc.plugins.asyncdrawing.enabled to false), but it doesn't work for me now.
I think it's because the flash player, since it's just crashed...
I'veupdated it today to version 22.214.171.124.
