[IDV #JPV-688019]: experiments with "try to add displays to current windows"

> Hello IDV folk.

> I found three odd behaviours which impact my plans to develop a personal

> multi-dataset integrations (overlays) easily.
> 
> 
> Attached are three bundles.
> Each contains a Z500 contour display. They are from 3 different reanalyses
> (using remote datasets, via aggregation .ncml files).
> 
> 
> * The 20C dataset hgt contours are pink, and its time driver is set to Jan 1, 
> 2010
> (by typing in Jan 2 and hitting Apply, which made the time driver widget say

> * The NCEP1 dataset hgt contours are blue and time driver is set to Jan 1.
> * The MERRA dataset h contours are green and time driver is set to Jan 15.

> 1. When I load either of the Jan 1 datasets, the display shows Jan 2.
> The time driver menu widget has a date problem.

This is fixed.

In the time driver design, one view window can only have one driver. It is not 
a good idea to 
try to add the two drivers through opening bundles. The good practice is to 
open the second view window and open the second bundle on the new window.

I don't quite understand the first half of this problem. The second half sounds 
like a bug, but there is a work around, you can open a new view window and load 
the bundle w/o driver to the new view window, and then kill the new window and 
create display on the first window. I think you can understand the trick of 
doing it this way.
