[IDV #VYP-183639]: IDV v4.1(u1): Time aggregation leaves *.gbx9 and *.ncx files in data source directory

Dave,
     In the IDV user preference, under System tab, there is a checkbox named 
"Write Grib Index in Disk Cache".
When it is checked (by default), the  IDV will normally cache grib data index 
sets to disk in the default directory: .unidata/idv/DefaultIdv/tmp/nj22. If you 
uncheck this box, the IDV will save those index sets to the same directory as 
the grib datasets. When you make the change, you need to restart the IDV for 
this change to take effect, and you need to make sure the write permission on 
this data directory. 
    Let us know if this is not what you experienced.
