Hi,

if I delete a control from inside ChildMouseEvent handler, the app will crash because Upp try to dispatch the event to it AFTER the control deletion :

Image Ctrl::MouseEventH(int event, Point p, int zdelta, dword keyflags)
{
	GuiLock __;
	for(int i = 0; i < mousehook().GetCount(); i++)
		if((*mousehook()[i])(this, false, event, p, zdelta, keyflags))
			return Image::Arrow();
	LogMouseEvent(NULL, this, event, p, zdelta, keyflags);
	if(parent)
		parent->ChildMouseEvent(this, event, p, zdelta, keyflags);
	return MouseEvent(event, p, zdelta, keyflags);  <---HERE
}

I don't know if a solution is possible, either.
By now I solved posting a callback from inside ChildMouseEvent instead doing the process there.
