Microsoft is looking for ways, in its BETA Search Product, to increase usability and features. Recently MSN launched this drop down search button that looks like this:

Most usability experts, I think, dislike drop down menus, I personally do not mind them. However, this does not work in IE for Mac or Safari. This is a screen sample from Safari.

There is forum discussion on the new button at Search Engine Watch Forums.
