Library Data Wizard Added Version 3.7.1 : Feature 3043 05/11/2007

A wizard facility has been added to ease the acquisition of library key data when no library keys, of the element type selected from the network diagram, are present in the project libraries. The wizard steps through the process of either... - creating a new library key - copying a library key from a library of the user's choice - copying a library key from the ERACS Reference Library ...then associates the newly created/copied library key with the selected network diagram element. Please see associated movie for additional information and further instructions.


Web Access Security Added Version 3.7.1 : Feature 3026 05/11/2007

A new security solution called 'Web Access' has been added to ERACS. This solution does not use a hardware security key (dongle).
