The new OSX version

Bug Report.

Not sure this has already been reported Michael, but when you are editing style in the Mac version and you select a "crayon" color and do not close the crayon menu and try and type the name of your new style, it doubles your letters. This does not happen if you close the crayon select menu.

Not a major bug for sure, but a slightly odd one.
