Here's what I know so far anout this browser problem from digging through
tons of aol7 traces.
Aol registers the WM_HTML_GETOBJECT message, which is usually used to create
an IHtmlDocument2 object, but then never uses the message returned from
RegisterWindowMessage.
08d10f38:Call kernel32.WideCharToMultiByte(00000000,00000000,70ccb00c
L"WM_HTML_GETOBJECT",ffffffff,405b53ac,00000207,00000000,00000000)
ret=70bd1cbf
08d10f38:Ret kernel32.WideCharToMultiByte() retval=00000012 ret=70bd1cbf
08d10f38:Call user32.RegisterWindowMessageA(405b53ac "WM_HTML_GETOBJECT")
ret=70bd4171

08d10f38:RET shlwapi.133: @(70ccb00c) retval = 0000c07b ret=70cca9d3
Also, at one point there are some UnmapNotify messages sent to an unknown
window, but I don't know if that's related.
0313-2:warn:event:EVENT_ProcessEvent Got event UnmapNotify for unknown Window
02400030
There's also a call to this undocumented function, but it since I'm using the
native dlls, it seems to work fine.
