By now I tried:

MSG msg = new MSG ();
while (Win32PeekMessage (ref msg, IntPtr.Zero, 0, 0, PM_REMOVE)) {
         Console.WriteLine ("Got a message");
          Win32TranslateMessage (ref msg);
          Win32DispatchMessage (ref msg);
}

On my Windows 7 machine, PeekMessage returns false.

Now that emulating DoEvents does not seem to fix it, I'm looking at the 
static constructor of XplatUIWin32, the class that also contains the 
"real" code for DoEvents. Besides initialization stuff, it creates a 
"foster window":

wnd_proc = new WndProc(InternalWndProc);
FosterParent=Win32CreateWindow(WindowExStyles.WS_EX_TOOLWINDOW, 
"static", "Foster Parent Window", WindowStyles.WS_OVERLAPPEDWINDOW, 0, 
0, 0, 0, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero);

Prepending that code to the workaround should make it work. I will 
create a test app ASAP.

Thanks,


Christian
