#9 A checkbox to make a diagnosis "common." What does that do? Or what is it supposed to do?
Well, I would call that a mystery, not a bug!

This looks to me like something that was meant to be a feature, but never quite made it.
(A means of marking diagnoses as common
could be helpful, if you could use that data to help you find diagnoses in the ICD-9 lookup.)
#10 On this one I think he means how, for instance, once someone has misspelled but saved "New Yourk" or "Etna" in a patients demographics screen, that item cant be removed from the system. I have a host of non-existent cities and insurance companies saved that I must be sure to bypass now when inputting demographics.
Gotcha.
Well, I believe there is a fix for this!
This is from the Help section of Amazing Charts:
I remembered stumbling onto this in the past, but I re-found it again today by searching under "misspelled".
Q: "There is a mispelled item in one of the drop down boxes!"
A: The drop down combo boxes in the Patient Demographic window are generated by finding all the unique entries for each patient. In other words, if you've spelled New York for one patient like "Neu York" then that spelling will appear in the drop down box UNTIL you find the patient under which you misspelled it, and fix it.
To find the patient(s) on whom you made the error, use the Search button at the top of the Amazing Charts Desktop, and lookup the misspelled word. Go down the resultant list and fix each misspelling, and the problem will be solved.
