This is the first time we've heard of anything like this so I'm a bit
stumped on what is happening.  It sounds like there is some sort of
graphics issue.

When you say the 3D model displays, what particular display are
you trying?  Is it a Plan View Contour or an IsoSurface?

What type of video card do you have?

What does the memory readout in the lower left corner of the IDV window
show while it's trying to load in the data?

What type of connection do you have to the internet?  Are you on
a dial-up line or on a cable modem/DSL connection?

If you only have 512MB of memory, you might want to change the IDV
script to use 256 MB maximum instead of the default of 512 Mb.  See
the instructions in the FAQ:

http://www.unidata.ucar.edu/software/idv/docs/userguide/Faq.html#faq1_cat3_11

for doing this.

Please answer the questions above and we can go on from there.
