Yes.  A bug snuck in at the last moment.  I put a bugfix out as a plugin.  Go 
to the Tools->Plugin Manager dialog and under Bug Fixes, install the WRF ARW 
fix for IDV 2.7.
It will look for files named wrfout_d01_.*.  If you have a different file name, 
you can select the WRF ARW netCDF files as a Data Source Type.

I'm going to send a message out to idvusers today.  I was waiting for 
confirmation that the fix worked.  Could you test that for me?

Note that in general we do not recommend using the native WRF output for 
anything other than quick looks.  It's best to run a post processor on the grid 
to destagger the grid and compute the standard meteorological variables.  See
