[solved] disable window resize with mouse, windowed mode?

how to do that?

Edit:
Solution

change in win32WindowMgr.cpp in (line 114)

PlatformWindow *Win32WindowManager::createWindow(GFXDevice *device, const GFXVideoMode &mode){
...

DWORD dwStyle = WS_CLIPCHILDREN | WS_CLIPSIBLINGS;
   dwStyle       |= WS_OVERLAPPEDWINDOW | WS_THICKFRAME | WS_CAPTION; 
   dwExStyle     = WS_EX_APPWINDOW | WS_EX_WINDOWEDGE;

to:
   dwStyle       |= WS_CAPTION | WS_SYSMENU & ~(WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_THICKFRAME); 
   dwExStyle     = WS_EX_APPWINDOW | WS_EX_WINDOWEDGE;
