Below, the data grid is set on the 2nd Look data set.  This requests 32 Blipmaps from Dr Jacks site.  In this case, all 32 are downloaded (green).  The yellow flags mean that the 4 and 7pm data may be available with a shorter, more reliable forecast period.  When you click on 'Get Yellow Data' the program would attempt to download these yellow flagged items from Dr Jacks site.
