Mandriva Linux 2008, 512MB; Alice 2.0.7.

When I try the "lunar lander" tutorial, Alice freezes at step 17. See the screenshot at http://evc-cit.info/alice/tutorial_hangs.png; notice the empty space where the "next" arrow should be at the top of the page.

When creating a world with a keyboard and monitor, the "top" view in quad view mode is extremely dark, and I can't seem to get the keyboard to appear in the left or front view; see the sceenshot at http://evc-cit.info/alice/dark_view.png; the a2w file in question is http://evc-cit.info/alice/monitor_keyboard.a2w
