c++ - Awesomium WebView doesn't display page -

i've made 2 simple classes use displaying uis awesomium. creating awesomium webview , setting parent window win32 window causes program hang , page never displayed. classes simple , creating window simple there isn't can think of going wrong. perhaps there else required i've done display webview?

to clarify: creating win32 window without creating webview works fine, window functions including drag code etc... hang happens when call set_parent_window.

have not used awesomium getmessage pumps messages webcore window. instead should pass null message pump dispatches messages windows created on thread.
