I had similar problem to easyrider. Quotes, weekly and daily charts were all frozen. However, intra-day charts were working normally!. Shutting down program with restart fixed problem. Ensign support had no explanation.
I am back to Sierra for backup. They dont have everything I want but they are hassle free. Three things I want in a charting package: idividually colored charts, alerts on studies, and the ability to scale your charts as you wish. Esignal comes close with the efs addons but none of the secondary packages have all of these. Its not a question of money. I would gladly pay up for these features. Maybe some day......
I went ahead and signed up for a month even with the problems I was having because Ive heard so many good things about this program and I was sure it was my own ignorance that was at fault. One week was not enough for my thick head to get the basics. Now that Ive had time to work things out in conjuntion with their great support I find that it has everything I wanted and more.
