// How to access properties with NS6/IE and with older NS:
// --------------------------------------------------------
// (1) Browser-Versions:
//   NS6:	navigator.appName = 'Netscape';
// 		navigator.appVersion = '5.0 (Windows; de-DE)';
//   IE5.5/Op:	navigator.appName = 'Microsoft Internet Explorer';
// 		navigator.appVersion = '4.0(compatible;MSIE5.5;Windows98;Win9x4.90)';
//   NS4.75:	navigator.appName = 'Netscape';
// 		navigator.appVersion = '4.75[de](Win95;U)';

// (2) Access Element div with id="vw1_1" (index) in Frame with name "Menue"
//   NS6/IE/Op:	obj = top.menue.document.getElementById('vw1_1');
//		obj = top.menue.document.getElementById(index);
//   NS:	obj = top.menue.document.vw1_1
//		obj = top.menue.document.layers[index];

// (3) Set Visibility
//   NS6/IE/Op:	obj.style.visibility = 'hidden';
//   		obj.style.visibility = '';
//   NS:	obj.visibility = 'hide';
// 		obj.visibility = 'show';

// (4) Set vertical position (y)
//   NS6/IE/Op:	obj.style.top = y;
//   NS:	obj.pageY = y;

// (5) Set Background-Color (white)
//   NS6/IE:	obj.style.backgroundColor = 'white';
//   NS:	obj.bgColor = 'white';
//   NS6/IE/Op:	obj.style.visibility = 'hidden';
//   		obj.style.visibility = '';
//   NS:	obj.visibility = 'hide';
// 		obj.visibility = 'show';

// (4) Set vertical position (y)
//   NS6/IE/Op:	obj.style.top = y;
//   NS:	obj.pageY = y;

// (5) Set Background-Color (white)
//   NS6/IE:	obj.style.backgroundColor = 'white';
//   NS:	obj.bgColor = 'white';
