Re: 20030625: IDV - Win 2000 Professional - Running IDV

Subodh,

Thank you for the detailed information. You have found a tricky but
important bug. With 1 gig of memory you should be able to easily display
10 frames of imagery. We will discuss this here among the IDV
developers.

The globe display is, at this time, a separate instance of the IDV. You
get it with the
instructions here:
http://my.unidata.ucar.edu/content/software/IDV/docs/UserGuide/IDV_displayingdata.html#globedisplay
Since you are using Webstart I will have to see how to do it and send
you word.
