I recently updated my app a bit (added a mute option for audio.play and other things unrelated to the controls),
and for some reason just ONE of the TWO webbrowser controls has begun to experience problems.
it will navigate for the first few times and then it will simply stop navigating.
after a time out amount of time it will give the standard IE page for no internet connection.
but no other internet functions of the app are timing out, and my connection tests are perfectly fine.
What could be causing this problem?
MarketSearchList as WebBrowser implemented in form Designer
that is completely the only code that refers to my WebBrowser control
and nothing else even talks to it.
Any ideas what could cause a webbrowser control to simply think it lost connection or fail to self-event?
