I've been testing this code:\n\n<IMG src="button.gif"\nonmousemove="return false;"\nonclick="return false;"\nonmouseout="src='button.gif'; window.status='it has been called'"\nonmouseover="src='down.gif';">\n\nIt appears onmouseout is not called when a mouse button is kept pressed\nwhile mouse cursor is brought outside the picture, but it is not true:\nonmouseout is called! To see it in action, bring mouse cursor over the\npicture with all its buttons released, then keep primary button down and\ntake mouse cursor outside the picture. You will see the text appear in the\nstatus bar!! but the picture will remain unchanged. This is because\nonmouseover is called just after onmouseout, when I see no reason for this\ncall to happen, and so restores the down.gif picture.\n\nIs that a bug from IE6??
