Please can you run through this quick sequence and see if you have the same problem as me?
Click on the patient icon
Open any pt file
Open the "appointments" tab to see prior appointments (you'll need to uncheck the "future appointments only" box)
Then open the "tracking" tab and make a tracking change (double click on any tracking category)
Do you see this error? "qryClient: Dataset not in edit or insert mode"
I am using FD version 126.96.36.199 data version 15.8.8, but the issue may appear in earlier versions?
Thanks for your help. Joyaa
