Opening Windows by JAVAScript

When you show a modal dialog the window remains on top of other windows until the user explicitly closes it.

window.showModalDialog("Test.html","dialogWidth:400px; dialogHeight:225px; status:no; center:yes");

When you show a modeless dialog the window remains on top of other windows, but you can still access the other windows.

window.showModelessDialog("Test.html","dialogWidth:400px; dialogHeight:225px; status:no; center:yes");
