Efficiency mode broken? about jsminesweeper

[tchesket]

It seems to freeze completely whenever I try to chord, not sure what's going on

Chording is done by left clicking the tile to chord.

Does it work okay when not in efficiency mode?

What size board are you using, efficiency can be very cpu intensive?

What browser are you using?

When the player stops responding can you go to the console ( right click somewhere off the board / select inspect / select console tab) and see if there are any errors or messages indicating a problem.

I've fixed the error when the middle mouse button is pressed.
