If I'm understanding you correctly, you're saying the Worklist button is disabled on the Patient screen is disabled? I think we might have all been under the impression that the Worklist configuration was not possible to get to for some reason.
If the Worklist button on the Patient screen is what you're trying to select, you need to go back into the DICOM configuration screen and check the BOX in front of the WORKLIST entry on the list of server connections. Then Save and Exit. Once you do that, your Worklist button on the Patient list screen will be ACTIVE and you should be able to select it. If there is no check mark in the box, the system doesn't recognize the device as an active server connection.
Same with any DICOM server used as an Archive. If there is no check mark in the box in front of your Archive Server, you won't be able to select that device to send to. If you use a shared network folder to store exams, you won't need to do this. You just have set up the drive as a choice to send to when you a) press the End Exam button or b) use the export button on the patient screen or exam review screen. You can also checkout the buttons tab of the Connectivity section to see if there are any other operations you want to customize by pressing P1 - P6, the Start Exam, End Exam or Freeze buttons.
Let me know if the pictures don't send properly, and I'll try something else.
