Last night Microsoft released an update for Windows 8.1 (KB3097877) and it seems to have caused an issue with the Treatment Card in Dolphin Management.
If you are having issues today, please uninstall this update.
Uninstalling Windows Updates
Once you get into Windows you can just head to Programs and Features and then click on “View installed updates” in the left-hand pane of the window. You could also search for that text if you prefer.
Then you can select the KB3097877 update and click the Uninstall button.
