Numbergrid disappears while movie-ad plays.

[HGN]

Using Chrome (latest version) and recently when doing Numbergrid Puzzle, the screen scrolls to bottom where a movie is playing. I realize that ads are where this site makes most of it's money, but that shouldn't keep one from playing the games.

I've looked for a fix and the only suggestion is to turn off Flash, which keeps the games from functioning.

Great site, and love the puzzles.
