Hi Rob-

You can use the Data Source Type dropdown in the File Chooser to 
set the type of file instead of renaming if you want.

Okay.  I'm cc'ing Robb Kambic to look into this. (Robb, I put the
files in the appropriate grib1 and grib2 directories under testdata).

Yeah, just after I sent my note, I noticed this also.

Okay, Robb will look at this.

Thanks again for the trace.
