I think I have found what you client may be running into. When creating a departmental mask, if you highlite the word "Departments" in the department view window and right mouse click, an option is available to Create Departmental Mask. You can create the mask and give it a description but the OK button will not activate. If you highlite an existing department in the department view window, then you can create the mask you want and the OK button will activate. If you highlite an existing mask in the department view window, you can only edit or delete the mask you highlited. It seems that you must create one department before before you create a mask.

Note that the help manual says otherwise, but this the only way that I could get it to activate the OK button on any Adagio station I have tried.
