Network link does not refresh.

[GoogleCodeExporter]

Happens if Google Earth is closed when network link is opened.

Steps to recreate. 
1) Close Google Earth. 
2) Open the network link from windows explorer. 
3) Google Earth will open, the network is displayed and refreshes 
once. 
4) Move around Google Earth, but the link never refreshes again. 
5) However, if you right click the link and select "refresh" the 
network link then behaves normally - it refreshes after motion has 
stopped. 

Using Google Earth version 4.3.7284.3916 (beta)
KML generated using asp.net on IIS 7 server

Sample Network link 
----------------------------- 
The attached example will generate a refresh from any location or 
altitude.  However, if you want to also see data, you need to be zoomed in 
close over the western United States.  For example,  34.449749°, -
118.609749° at a range of 13315m works fine.

If you add "refreshMode" and "refreshInterval" to the "Link" (formerly known 
as "Url") node the view refresh onStop works fine.
You can define a very high interval in "refreshInterval", so actually only the 
onStop refresh will apply.

Excellent!

This also fixes the related issue #190, "Icons do not display".

Marking as fixed, see posted workarounds.

• Changed state: Fixed

Update: This problem also exists if viewRefreshMode is onRequest.  The above 
workaround does not fix the problem.
