The screensaver applet is basically just like the one in Windows 3.0 With Multimedia Extensions.

Being such an early pre-release, there are obviously several bugs. For some reason, attempting to test the Blank Screen screensaver causes this particular error. Clicking ignore several times allows you to test as expected. This doesn't occur with any other screensaver.

Amusingly, simply closing the screensaver applet also causes the entire Control Panel to crash.

This is the wallpaper selector control panel applet, which is quite different from earlier releases.

This build also includes this drag and drop printing functionality, which creates icons for each installed printer and allows you to print simply by dragging and dropping things to the printer icon. Of course this won't work if you have no printer.
