[netCDFJava #CZW-502913]: combining satellite bands via ncml



Hi Joleen,

I'll be doing my best to help you.  Whenever tools are used across their 
original purpose, the results become less than predictable. Also, an 
issue like using the middle mouse button is more of an artifact (and 
much trickier to manage) than a concrete problem /per se/.  I don't know 
what will happen with that, but I have sent it over to the IDV team for 
consideration.  It may be that some information in the new files is 
different or missing compared to the old files.  I'll let you know what 
I find.

Cheers,
   Lansing
