program will not close

[WBaumgartner]

Hello, I am new to Knoppix, and I am having a problem. Whenever I open Frozen Bubble (the only program I've have trouble with so far, but there may be others), it will not close, no matter what I do. I have verified the checksum on the original download, and I ran testcd to verify the cd itself, everything seems fine. What can I do to fix this?

Also, is there a way to boot Knoppix and skip hard drive detection/use?
