I decided to call the current update 0.9.2 instead of 0.9.1.1 to indicate that this isn't just a minor update but brings two new major functionalities: printing and dicom-tag-modification. Furthermore some bugfixes are included and the viewer stability is improved a lot.
Tip: try the new drag and drop options in the main form: drag, for instance the patient-id of a patients study onto the ID search field to search for more studies of the same patient.
Thank's to the help of Tim from the US, K-PACS is now compatible to the CDMEDIC dicom server (unix-based). If you want to learn more about this server, go to http://www.idoimaging.com.
