Thought I would pass this on. Not sure if it has been logged yet or not. Sometimes when building a line chart, the properties field locks up when I try and select the "text" tab. The dialog boxes in the "text" tab do not show up and the "layout" tab is also highlighted. I do not know what causes this, but it has happened to me numerous times. The only solution is to totally delete the line chart and start all over. It may be related to copying and pasting. I set up a chart the way I need it and then copy/paste it rather than making all the changes on a default settings chart when I need another chart.
