js code:
var WndCommandBar_Shell = MsgPlus.CreateWnd("Windows.xml", "WndCommandBar_Shell", 0);
var WndCommandBar_CMain = MsgPlus.CreateChildWnd(WndCommandBar_Shell, "Windows.xml", "WndCommandBar_CMain", 12, 2);
var PosInfo = RetrievePos(WndCommandBar_Shell, "PlhChild");
Interop.Call("User32", "MoveWindow", WndCommandBar_CMain.Handle, PosInfo.X, PosInfo.Y, PosInfo.Width, PosInfo.Height, true);
Seems to get stuck (Messenger doesn't crash, but the debug doesn't get any further than "Script is starting", and the window appears and then disappears again).
