I, and my staff, have been more bothered by one problem more than any other issue in AC! If anyone goes to save the chart and accidently mouses the option right above 'save,' which is close the chart, it will actually close and lose the chart. It will trash it and often not even ask if you want to save it. I don't know why it asks at some times and not others. Further, if you navigate to other tabs like the 'imported items', get caught up in what you are doing and accidently hit the 'red X', it trashes the chart and you have just lost half an hour of typing, including the vitals and everything else. AC really needs a better warning system and get rid of that 'red X' and replace it with a 'blue save' button. The default should be saving it back to the message inbox where I got it! Are you listening AC? This was a big problem when I started using the system, but I've had to be trained to stay away from these dangerous buttons. Occasional my staff still groans when I ask for the vitals again, knowing I just lost the whole visit. When I train new staff members, expect charts to get lost. Further, I can't send them back to the staff for any reason without fear that all my work will be lost. AC needs to make it much more difficult to erase charts.
