Hi. I'm using this under the latest Windows 7 (b.6956) and the grid lines refuse to disappear. Is this a bug or an issue with Windows 7 or something else? I've tried with the regular and portable versions. One quick fix is to make the text the same color as the background but that leaves an empty space to the left.
It would be nice if there was an option to remove the scale numbers on the left hand side as well.
