For me, F5 = diseases. F6 = surgeries/procedures. so if I hit F5 then without closing it, hit F6 ... then close the surgeries window ... when I click on the diagnoses to display details ... no details will display. Closing the window and reopening it will allow the details to be checked. No biggie .. but FYI.
Yes, that will happen because I reuse variables in these screens. So, you shouldn't have both of them open at the same time .. as then the last opened only will work
