Standard browser object getting a 'Com Exception - Required Resource is in use.'

[Mufasa]

I've got a browser object ( the standard one in VS ) that plays assorted
stuff. When it goes to a specific website, I'm getting the following error:

While attemping to set Frame A on machine ECS2059421 to
'http://image.weather.com/looper/archive/us_radar_plus_usen/2L.jpg?1176238592046'
got an error. Error Type: System.Runtime.InteropServices.COMException
Error Message: The requested resource is in use. (Exception from HRESULT:
0x800700AA)
Stack Trace: at SHDocVw.IWebBrowser2.Navigate(String URL, Object& Flags,
Object& TargetFrameName, Object& PostData, Object& Headers)
at AxSHDocVw.AxWebBrowser.Navigate(String uRL, Object& flags, Object&
targetFrameName, Object& postData, Object& headers)
at ECS.winECS.SetFrameA() in c:\marlin\software\ecs\ecs\winecs.cs:line
1842

The page plays fine in IE.

That line of code is the objBrowser.Navigate method.

Anybody have any thoughts why this would happen?

TIA - Jeff.
