[idvusers] Problems reading changed grib-files

I'm currently trying to convert some netcdf-files to grib. Therefore it is really nice to be able to visualize both files with idv (2.5 on linux).

This works as long as I don't reuse filenames with data of different projections. In that case, I get a null-pointer exception when opening the file. Restarting idv does not help, but deleting all files in ~/.metapps/DefaultIdv/tmp/nj22 does.

Would it be possible to delete those temporary files when removing the datasource, or quitting IDV?

Best regards,
