Just press space and hope it doesn't glitch up.
M'kay so you guys tell me, do you see what Scratch is SUPPOSED to be showing or something totally different? The first slide is suposed to be showing a polar bear. (Beautiful rite?) The second says a bit of text, and the last one says OH MY GOD BECKY! Please tell me what it shows you, I need to make sure Scratch can work properly for any viewer/watcher people.
