A: If the statistics button is greyed out then make sure that the Data>Select Variables dialog has some data columns selected.  If no statistics are displayed after clicking on the Statistics button on the main Toolbar and select the Display Statistic Selection button on the RHS toolbar and make sure that the desired statistics are checked in here.  If problem persists delete all the *.gst files in the install directory if you’re running ioGAS version 4.4 and older, or delete all the *.gst files in the user configuration directory (C:\Users\username\AppData\Roaming\ioGAS\state) if you’re running version 4.5 or later to reset and re-start the program.  One of these files is a cache of the chosen stats which may have become corrupted.
