I use 11 every day now to get a quick look at my position trades and investments in a 20 chart page. I thought it was robust in this simple application. Haha! I decided to change the look of the candlesticks. So I selected a chart, went to Format Object. Made the change. And selected Apply All. It correctly converted 19 of the charts, but made the candlesticks invisible on the 20th. What on earth are they going to show people in February in New York? A carefully-vetted page example? Better not let anybody touch it!
