I have not experienced this error. I have not had a problem where the chart has not reopened when I have had to shut down. I would get Tech to look at the log and see if there is an error recorded. Try and keep the date and time so they can pinpoint in the log easier where this is happening.

The only freeze/shut down I am still experiencing is when I go to print. Occasionally AC will lock up and not allow me to send the print request. I have to open task manager, close AC and restart but the chart comes back to the stage just before I put in the orders to be printed. I had tech look but it does not appear to be an AC issue more of an issue with the setup. No real explanation available!
