Sometimes it restarts but most of the time the whole system hangs. Berkeley Pacman here: Info: http://ai.berkeley.edu/search.html Source: https://s3-us-west-2.amazonaws.com/cs188websitecontent/projects/release/search/v1/001/search.zip I found that commenting out line 217 in file "graphicsUtil.py" fixes the problem (yet alters the game). Of course there may be bugs in the software, but those bugs should never be able to hang a system.
