Sometimes while I working on a lab, the World (not the objects) will completely disappear and the only way I can get it back is to back up with ctrl-Z. Any suggestions for this?

Also, what is the difference between a .a2c file and the world files, .a2w. On the disc with the main textbook, there are .a2c file types, but I cannot open them in Alice.

Thank you!
