Network link fails to refresh

[Jared]

I have a network link that grabs streaming KML from an ASP script. It
refreshes onStop but sometimes it fails to refresh and you have to
manually tell it to refresh. It usually stops refreshing right after
the first placemarks are displayed but after you refresh the network
link manually it works fine. I have noticed the same problem on
another person's Network Link that works in a similar way. Is anyone
else having this issue? Is this a problem with Google Earth or am I
doing something wrong? Is there a workaround? I am using GE version
4.3.7191.6508.

Thanks in advance

Hi Jared,

Can you post a sample of the code you're using?

Hi Jared,

Actually, I can't really replicate this, can you point to your actual
site?

BTW, for forward compatibility, change the <Url> element to <Link> and
drop the ? at the end of your URL.

Oh, and have you checked your access logs to see if it is hitting your
server?

Yeah, it works at first but then stops. I have tested it on several
different machines. I put the site up on a test server.

Zoom in on Oklahoma City until you see placemarks and then you should
notice the problem.

Hi Jared,

I tested this out, and it seems to work fine for me. You're using
Windows, correct? Is there anything about your local machine that
might cause issues? Like firewall settings, etc?

You can check the access logs from me, I hit it around 9:48PST, up to
about 9:54.

Did it continually refresh for you? I have the same problem on a Vista
Business machine and XP Pro on three machines in different physical
locations. So I would be suprised if it was just a local issue. I'm
not sure if you understand the problem. You should be able to scroll
aound Oklahoma and have the KML continually refresh the placemarks in
the view. My problem is it doesn't keep refreshing. You have to
manually refresh it once to keep it working. It happens in every test
environment I have tried it in. I also know of another persons
program that works the same way and has this problem.

Thanks for your help,
Jared

Hi Jared,

Yes. I just tried it again, I'm able to navigate around Oklahoma just
fine. In fact, I did it several times, just tried it again.

I'll try testing it on another machine when I get a chance. Just out
of curiosity, and this shouldn't matter, but have you tried switching
between OpenGL and DirectX?

Mano

[Jared]

Yeah, I have have an XP machine that I use OpenGL on and the rest I
use DirectX but I will try to check both on all machines later. This
is very curious, I have had several people test it with same problem.
I guess it is a good thing that not everyone is affected but I would
like to get to the bottom of it. I'll let you know my results.

[Jared]

Still no luck with switching between OpenGL and DirectX.

[ManoM]

Hmmm... Still can't replicated it. I had a colleague try it too, and
she didn't have any problems.

Mano

[Jared]

Okay. Well, thanks for your help, I guess it is working.

I have exactly the same problem.

The OnStop NetworkLink stops refreshing about after the first or
second update.
After once being restarted, it continues to work fine and no longer
fails.
