[IDV #TPP-254601]: More details on "Sunday" problem with OPeNDAP and/or THREDDS



Good question. Being new to the IDV team, I can't really say why it's like 
that, but my guess is that there just wasn't a good place to put it in the 
lower right control tab. Out of curiosity, how often do you you the lat/lon 
bounding box vs the rubber-band tool?
